Fix CTA button text invisibility on course detail pages

The .course-detail a rule was inheriting onto .cta-button due to
higher specificity (class + element > class alone), making button
text the same color as the button background.

Scoped the .course-detail a rule with :not(.cta-button) so it
no longer matches CTA buttons.
