This will allow us to find broken links easier since if we remove or change
the location of a particular page that's linked in another, then Hugo will
throw a warning/error when this happens if we are using the ref functionality.

The only link that I'm not dealing with here is the one for tips for bug
reports since that page hasn't yet been ported to the new nest site.

Ran dev-server.sh and verified the links that got changed in this PR still worked as intended.
