Make links in code blocks inherit syntax highlighter colors

See #3335 (comment) and preceding discussion.

Please let me know if there's a better place/way to make this exception. I couldn't tell if there were any particular SASS conventions I should be following.

With this change links in code are effectively invisible other than a cursor change. They weren't especially noticeable before (despite looking at the docs many times over the years I'd never noticed these links), so this isn't exactly a regression, but I'll happily make further style changes¹ if desired.

Footnotes

1. My first thought is a :hover effect (like adding an underline). That only helps after the link has been pointed at, but makes it more apparent that they're clickable. ↩

They are supposed to give a hover of the description, but it looks like that isn't happening - its probably not worth blocking the PR but I'll see if I get some time next week to bring that back up to working
