Buttons: Improve the .button-link CSS class for link-like buttons.

Updates `.button-link` adding color and underline to make link-like buttons look
like links by default. Introduces `.button-link-delete` as a modifier, stackable
CSS class for red button-links.

Props Cheffheid, afercia.

See #34242.
Fixes #35126.
