I don't think we have badges for quay.io yet.
I think I will keep the existing Docker Hub badges for now.

In theory, I should be able to merge this PR to my fork main branch, and it should work fine. I will give it a try :)

I created all the images in Quay, robot and had to create org.
Maybe I will have to move my repos to my newly created org to make everything work, but I'm not sure yet.

I caught at least one bug with this idea to test everything in my fork first.
