Update the formatting of links and add a Markdown render hook for
handling relative internal links. Cross-references between markdown
files are now resolved the same way in both GitHub and Hugo.

I was reading https://distribution.github.io/distribution/recipes/mirror/#gotcha when I noticed some unexpected annotations after the "fair use policy" link. According to [Stack Overflow](https://stackoverflow.com/a/4705645/6571327), these are kramdown options that the current hugo documentation site isn't respecting. I searched the hugo docs and couldn't find an easy way to preserve `rel="noopener" target="_blank"` behavior, so I removed the annotation.
