- Enable RFS
- Add documentation
- Disable doc font size overrides

This is a follow-up to #29322, specifically "allowing easy placement of
the `.form-check-input` in more places."  In my testing in Firefox and
Chrome, setting `vertical-align: top` removes the need to add
`float-left` to vertically align the checkbox and label text.  And doing
so does not visually affect examples which do apply `float: left` via
nesting in a `.form-check`.

Fix typo

* v5: Simplify navbars by requiring containers

* Update migration docs for navbar

Use our example shortcode's `class` parameter instead.

* Remove mention of icons from migration since they're not part of the core project

* Cleanup icons page to mention Bootstrap Icons

* Add variables for shades and tints of each major color

* getting-started/theming.md: use a `range`.

Add optional `$color` argument to `button-variant()` and
`button-outline-variant()` for additional flexibility.
