ALKiln: Links in Section titles don't show up in the sidebar

[BryceStevenWilley]

See https://suffolklitlab.org/docassemble-AssemblyLine-documentation/docs/alkiln/setup#githubNyou-details

I.e. the link of "GitHub+You ™️" doesn't show up in the side bar. Not the worst, but without it, many of the sections on that page just read "tests" or "test details".
