Twenty Twenty-One: Replace the experimental link color theme support.

This replaces `add_theme_support( 'experimental-link-color' )` with `add_theme_support( 'link-color' )`, to provide the feature to Twenty Twenty-One users, but 
also to avoid throwing a "doing it wrong" message when Gutenberg version 16.2 is active.

Follow-up to [58597].

Props poena.
Fixes #58702.
