ci & tests: Use registry.fedoraproject.org for Fedora container images

[travier]

The plan is to keep using the registry.fedoraproject.org name but redirect it to quay.io.

Sorry - the above isn't that obvious. I'm referring to the fedora-minimal:39 which still feels outdated. I understand this is only addressing the registry.fedoraproject.org change - I am wondering if we could do both here?

Thanks! I'll add the 39->40 change to this PR.

Looks like I pushed it right after :)

The only concern I have with this "redirect" plan is that it now makes our image pulls dependent on both registry.fedoraproject.org and Quay.io working, instead of just the latter. For that reason alone, I'd vote to just keep using Quay.io. ISTM like the main goal of the redirect approach is to not break existing docs/code, which is not a concern here since we've already done the work to move them over.

It's also weird because we push directly to quay for our FCOS images. Inconsistency isn't great.

Let's do #2990 first and then we'll see for this one.
