doc: underline links

The current use of color only to differentiate links fails WCAG A accessibility standards. Possible solutions are: 1. Using a text indicator to show that the text is a link. 2. Using additional cues (such as underlining). 3. Providing color contrast of 3:1 or greater with surrounding text (not the background--the adjacent text!) along with visual cues on hover. The solution here implements the second option.
