In f7f78023e we added new variables to the Vector 2022 variables
that overrode the defaults, but forgot to preserve the defaults
in Vector legacy. This resulted in changes documented in
T213778#8181795
Going forward it makes sense to separate these.

These overrides are now redundant now that Vector and Vector 2022
are separate skins.
This override was technical debt, but is now causing inconsistency
in styles as a result of T315321
These are now defined in the variables file instead.

Follow Web Content Accessibility Guidelines and
use Wikimedia Design Style Guide colors with
at least 3:1 contrast with surrounding body text.
Also unify external and normal links as the color difference is
basically opaque to understand beyond a small group of power users.
