feat(markdown): Underline links in body content
Purpose
At the moment, links in the markdown content are not underlined and have low contrast next to static text. This makes it more difficult to discern a link from surrounding text.
Solution
A boring solution is simply to leverage the default text-decoration: underline
for links within markdown. This is also proposed as an update to markdown in GitLab UI gitlab-org/gitlab-ui#1084, but this solution covers the gap until that is updated and Pajamas is using the markdown styles in documentation.
