Replacing 'mediawiki.ui/variables.less' @import with
new skin-aware 'mediawiki.skin.variables.less' standard.
Removing calls for 'mediawiki.skin.variables.less' in favor for
'minerva.variables.less' for consistency.
Also
- replacing several static values with new Codex design token featuring
skin variables of `background-color`, `color`, `border-*` and
`transition` categories
- renaming several Less variables to variable naming standard
- moving a small number of MinervaNeue specific variables into
'minderva.variables.less' file. Those should be replaced in mid-future
by Codex design tokens
Please note, that this patch is not replacing all values with
possible Codex tokens. It's just applying them on selected
categories for consistency for now to keep the patch easier reviewable.
Further replacements will be done in follow-up patches.
Bump MediaWiki core required version to >= v1.41.0.

* Add @font-size-minerva-smallest and use it in place
of font-size: 0.8em across the site so that we get a round
number for our font sizes.

* Remove ambiguity in imports - say the file extension
'less' for all instances of variables and mixins.
* Separate toast styles from drawer styles so they can be
imported separately
* associate header-action selector with its parent
(.overlay-header) not parent's parent (.overlay) so it can be imported
and rendered without the Overlay.
