Is your feature request related to a problem? Please describe.

Buttons in forced-colors mode lack a border or different background color which would add context as well as clarify how large the button target is.

Describe the solution you'd like

Adding outline: 2px solid transparent would add a border to buttons and would be consistent with existing forced-colors styles

Describe alternatives you've considered

There is a ButtonFace system color which is intended to contrast between the face of the button and the ButtonText. In default forced-colors light and dark themes, this color is the same as the default background color and therefore blends into the background with no visible change.
