Lennard Hofmann 8d24041c1a rc markdown: Fix HTML highlighting in inline code
Because the HTML highlighter was higher up in the hierarchy than the code
highlighter, it took precedence. I fixed it by making it an inline region.
Using my new knowledge of "inline" I was able to remove one line of code.

Fixes #4091
