Deprecate this image

Ok looks like this is coming in F42 so we don't need to make this here: https://pagure.io/fedora-infra/ansible/pull-request/2502

Taking a quick look at the pulls doesn't show a ton of users so I think we can call this experiment over.

Sure, I'm for deprecating the image.

Anything I can do to help in the process? Do we need to redirect users to a different ublue image and/or the upcoming official image?

I think we just edit the README and leave a link with the bootc switch instructions on it. Then we leave a note in the release notes/announcement for F42.

Maybe link to m2os and secureblue? they both have cosmic images available.

And maybe to yours as well? https://github.com/castrojo/bazzite-cosmic
