UDS-1630: fix(unity-bootstrap-theme): remove problematic anchor styles

[tbutterf]

UDS-1630

Description

The previous PR was insufficient to solve the problem. So, we're trying again. In a post-scrum we decided that the best path forward was to remove these styles, as they were overgeneralized and were causing problems with basic functionality. Removing them doesn't seem to have caused any problem, but we should pay attention to Percy to see if any unanticipated visual regressions occur.
