Is this going to pollute the CI registry with tons of untagged images? Let's think afterwards about how to optimize this.

I do not know how ghcr.io treats untagged images, I hope they are "garbage collected", also it would only happen when this workflow runs which (after the period of high initial activity) won't be hopefully that much.
However I agree this needs to be addressed, which is why I put a TODO in the next line.
I am thinking of building and pushing these images in a separate workflow, and this one would simply use tagged image e.g.
ghcr.io/xrplf/ci/debian-gcc:12-bullseye. These won't be updated often (in fact, once or twice per months seem realistic) so we do not need to remember their digests etc. because, with this rare rebuilds, network race conditions won't bother us.
