anubis: rename anubis-el8 to anubis-el and see about enabling on download

Looks like the scrapers are hitting the download servers now.
So, look at setting up an anubis pod there like we did for pagure.
anubis package isn't available for epel9, so we just use the container.

Will test this with dl01 and tweak until it's working.
