Disabled link cleanup (#34886)
* Disabled link cleanup

per https://www.w3.org/TR/html-aria/#docconformance

> It is NOT RECOMMENDED to use `aria-disabled="true"` on an `a` element with an `href` attribute.
>
>NOTE
>If a link needs to be "disabled", remove the `href` attribute.

This PR removes the unnecessary `href="#"`, `tabindex="-1"`, and `aria-disabled="true"` from disabled links in both docs pages and examples. `aria-disabled="true"` *is* kept for disabled link-based buttons (that have `role="button"`) as there it's appropriate to use (you *want* to convey to assistive technologies that this thing you're claiming is a button is also disabled at the moment)

Further, the PR extends the "Link functionality caveat" to show the "proper" way (removing `href` and adding `.disabled` class only) to disable a link, but then explains what to do if that's not possible (and then keeps an example with all the traditional `href="#" tabindex="-1" aria-disabled="true"`, but explains clearly that it's not ideal). Same sort of explanation is also added to the pointer event utilities page

## Overview
We use a large block of connected links for our pagination, making links hard to miss and easily scalable—all while providing large hit areas. Pagination is built with list HTML elements so screen readers can announce the number of available links. Use a wrapping `<nav>` element to identify it as a navigation section to screen readers and other assistive technologies.
In addition, as pages likely have more than one such navigation section, it's advisable to provide a descriptive `aria-label` for the `<nav>` to reflect its purpose. For example, if the pagination component is used to navigate between a set of search results, an appropriate label could be `aria-label="Search results pages"`.
{{< example >}}
<nav aria-label="Page navigation example">
<ul class="pagination">
<li class="page-item"><a class="page-link" href="#">Previous</a></li>
<li class="page-item"><a class="page-link" href="#">1</a></li>
<li class="page-item"><a class="page-link" href="#">2</a></li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
<li class="page-item"><a class="page-link" href="#">Next</a></li>
</ul>
</nav>
{{< /example >}}
## Working with icons
Looking to use an icon or symbol in place of text for some pagination links? Be sure to provide proper screen reader support with `aria` attributes.
{{< example >}}
<nav aria-label="Page navigation example">
<ul class="pagination">
<li class="page-item">
<a class="page-link" href="#" aria-label="Previous">
<span aria-hidden="true">&laquo;</span>
</a>
</li>
<li class="page-item"><a class="page-link" href="#">1</a></li>
<li class="page-item"><a class="page-link" href="#">2</a></li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
<li class="page-item">
<a class="page-link" href="#" aria-label="Next">
<span aria-hidden="true">&raquo;</span>
</a>
</li>
</ul>
</nav>
{{< /example >}}
## Disabled and active states
Pagination links are customizable for different circumstances. Use `.disabled` for links that appear un-clickable and `.active` to indicate the current page.
While the `.disabled` class uses `pointer-events: none` to _try_ to disable the link functionality of `<a>`s, that CSS property is not yet standardized and doesn't account for keyboard navigation. As such, you should always add `tabindex="-1"` on disabled links and use custom JavaScript to fully disable their functionality.
{{< example >}}
<nav aria-label="...">
<ul class="pagination">
<li class="page-item disabled">
<a class="page-link">Previous</a>
</li>
<li class="page-item"><a class="page-link" href="#">1</a></li>
<li class="page-item active" aria-current="page">
<a class="page-link" href="#">2</a>
</li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
<li class="page-item">
<a class="page-link" href="#">Next</a>
</li>
</ul>
</nav>
{{< /example >}}
You can optionally swap out active or disabled anchors for `<span>`, or omit the anchor in the case of the prev/next arrows, to remove click functionality and prevent keyboard focus while retaining intended styles.
{{< example >}}
<nav aria-label="...">
<ul class="pagination">
<li class="page-item disabled">
<span class="page-link">Previous</span>
</li>
<li class="page-item"><a class="page-link" href="#">1</a></li>
<li class="page-item active" aria-current="page">
<span class="page-link">2</span>
</li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
<li class="page-item">
<a class="page-link" href="#">Next</a>
</li>
</ul>
</nav>
{{< /example >}}
## Sizing
Fancy larger or smaller pagination? Add `.pagination-lg` or `.pagination-sm` for additional sizes.
{{< example >}}
<nav aria-label="...">
<ul class="pagination pagination-lg">
<li class="page-item active" aria-current="page">
<span class="page-link">1</span>
</li>
<li class="page-item"><a class="page-link" href="#">2</a></li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
</ul>
</nav>
{{< /example >}}
{{< example >}}
<nav aria-label="...">
<ul class="pagination pagination-sm">
<li class="page-item active" aria-current="page">
<span class="page-link">1</span>
</li>
<li class="page-item"><a class="page-link" href="#">2</a></li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
</ul>
</nav>
{{< /example >}}
## Alignment
Change the alignment of pagination components with [flexbox utilities]({{< docsref "/utilities/flex" >}}).
{{< example >}}
<nav aria-label="Page navigation example">
<ul class="pagination justify-content-center">
<li class="page-item disabled">
<a class="page-link">Previous</a>
</li>
<li class="page-item"><a class="page-link" href="#">1</a></li>
<li class="page-item"><a class="page-link" href="#">2</a></li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
<li class="page-item">
<a class="page-link" href="#">Next</a>
</li>
</ul>
</nav>
{{< /example >}}
{{< example >}}
<nav aria-label="Page navigation example">
<ul class="pagination justify-content-end">
<li class="page-item disabled">
<a class="page-link">Previous</a>
</li>
<li class="page-item"><a class="page-link" href="#">1</a></li>
<li class="page-item"><a class="page-link" href="#">2</a></li>
<li class="page-item"><a class="page-link" href="#">3</a></li>
<li class="page-item">
<a class="page-link" href="#">Next</a>
</li>
</ul>
</nav>
