Cleanup the Fedora 36 mirror content

This is mostly a formality as upstream of us the content was already
removed and we synced that removal. But this will do a little extra
cleanup for us to make it look even less like a mirror of Fedora 36.

I also kept the structure of the file rather than deleting the code to
sync Fedora content. This should make it easy for someone to pick this
back up in the future if there is a need and ability to maintain it.
