Featured Items: Remove inline style defaults for color options (#7036)

* Remove inline style defaults for color options.

This replaces the inline style with an added editor-specific styling
with slightly more specificity - but not too much to where it overrides
the Site Editor.

* Remove additional styles from editor stylesheet.

These styles are meant to apply to both the frontend and the editor. The
ruleset was originally added to the editor stylesheet to add an
additional layer of specificity but it was decided that this is
unnecessary.
