1. Instead of having two selectors, we use the `.list-group-item` class and have coverage for list items and anchors.
2. Rather than override all border values, we only override what we set with `border-top`.
Fixes#23360 by restoring just the offset class generation to our grid
framework mixins. Also restores the `make-col-offset` mixin.
Docs have been restored to illustrate this behavior and merged with the
newer margin utilities examples.
I suggest removing `color: #FFF` from the `badge` class, because it is
provided by the `badge-<modifier>` classes along with a
background-color, whereas there is no corresponding background-color
provided on the `badge` class itself.
Background
----------
According to the documentation:
> [badge] Requires one of the contextual, color modifier classes for `color` and
> `background-color`.
That is, color and background color should be provided by a modifier
class, rather than the badge class itself.
e.g. `<span class='badge badge-primary'>4</span>`
In general, providing a `color` property without also providing a
`background-color` should be avoided. [W3 QA tips]
In this context, this is a problem only if someone creates a `badge`
without providing a modifier. Such an omition may be difficult to trouble-shoot,
because this will most likely yield white text on a white background.

Uses some if/else action to ensure there's readable text on hover. Swapped out a hex value to a variable while I was in there.
Fixes#23398, fixes#23351.
* Remove remaining references to v4 Alpha
This commit removes the remaining refrences to the v4 Alpha website and replaces them with the
corresponding v4 Beta ones.
**Note:** We have to hard code the current docs version at some places. Wouldn't it be good to have a `/docs/latest/` redirect to solve this "issue" in the future?
