It's not easy to otherwise correlate the examples with the relevant classes: you'd have to mentally count and correlate them. This obviates that need. Please see the image below to see the usefulness of the above.

* Use aria-labelledby to associate form-text (helper) with input field when it contains mandatory info (e.g. data format)

* Example in input-group needs aria-describedby (or aria-labelledby) too

* Docs: handle light/dark mode in Algolia search modal

* Improve scopes

See https://github.com/w3c/wcag/pull/1780

Closes #37022

* Update hero button color

* Fix link color on examples index

* Move .bd-btn-lg to docs buttons partial, move larger border-radius to that class so medium buttons don't look odd

* Undo the markup split

* Round padding up to whole number

* Use $navbar-light-color instead of inline color

* Introduce separate $navbar-light-icon-color

Explicit labelling (which then would also benefit from a `role="group"` or similar role) is only optional, and not really appropriate just for a cheatsheet

Closes #37591

* Fix social image URL to be absolute

* Deduplicate social.html

* Get image dimensions with Hugo

Also, add missing `'use strict'` statements; these aren't real modules.

* @babel/cli   ^7.19.3  →  ^7.20.7
* @babel/core  ^7.20.5  →  ^7.20.7
