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.

Ieebc40073eb3d0c8a56ebc8aec3f060199943ddc lowers the breakpoint
at which search will break into 2 columns (search + interwiki),
in large part because the 2nd column will also be occupied by
Extension:SearchVue's side panel.
On mobile, Extension:SearchVue presents differently (directly
below a search result), so there's not as much need for a 2nd
column this early - wider search results are prefered.
