Styling of hyperlinks in content relies on color only (a11y) #4939

Describe the Bug

In default style, hyperlinks are distinguishable from regular text only by color, which is not enough and problematic from an accessibility standpoint (think colorblind).

Note that in info boxes, there is underlining on links.

Underlining on hover is not enough.

Steps to Reproduce

Expected Behaviour

underline links in content column.
