Replacing Vector specific variable with standard token that is meant
for exactly the applied use cases.
Note, I've left `border-color-subtle-transparent` because of that
extra engineering leg. I assume it was meant for animating the property,
which is not there. It seems better to me to replace this variable too
with `border-color-transparent`.

Removing 'mediawiki.ui/variables.less' `@import`, which is now
fully replaced by skin-aware 'mediawiki.skin.variables.less'
standard.
Bumping required MediaWiki core version to >= v1.41.0.

This removes CSS selectors associated with the Page tools
feature flag, i.e. `vector-feature-page-tools-disabled` as
well as `vector-feature-page-tools-enabled` by removing
the 'disabled' styles and integrating the 'enabled' styles
into the default page tools code.
