Patrick H. Lauke 00ff5b83f9 Add explicit aria-label to unlabeled controls
- in particular, controls that just relied on `placeholder`, as this is still not officially/consistently supported as a valid way to provide an accessible name (though some browsers do use it as a fallback)

## Default
Custom `<select>` menus need only a custom class, `.form-select` to trigger the custom styles. Custom styles are limited to the `<select>`'s initial appearance and cannot modify the `<option>`s due to browser limitations.
{{< example >}}
<select class="form-select" aria-label="Default select example">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
{{< /example >}}
## Sizing
You may also choose from small and large custom selects to match our similarly sized text inputs.
{{< example >}}
<select class="form-select form-select-lg mb-3" aria-label=".form-select-lg example">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
<select class="form-select form-select-sm" aria-label=".form-select-sm example">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
{{< /example >}}
The `multiple` attribute is also supported:
{{< example >}}
<select class="form-select" multiple aria-label="multiple select example">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
{{< /example >}}
As is the `size` attribute:
{{< example >}}
<select class="form-select" size="3" aria-label="size 3 select example">
<option selected>Open this select menu</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
{{< /example >}}
