Nah right now it's intentional that we are defaulting to the latest.

Hmm you know if we wanted to do anything else, what we should really do is have renovate bump it, though that quickly escalates into "bump our pinned mirrored images" anyways

And argh we are going to emit this warning because latest is 44 not 45 so fix that

if [[ "fedora-${fedora_latest}" != "fedora-45" ]]; then
echo "::warning::Fedora latest is now ${fedora_latest}, but CI is expecting 45. Update CI configuration."
