Subject: [PATCH] Administration: Update hover and focus states in admin menu.

This adds a border along the side of admin menu links when hovering or focusing on them, as color should not be the only indicator of link state.

Props accessiblejoe florianziegler afercia rianrietveld michael-arestad ryan hedgefield audrasjb ibdz.
Fixes #28599.
