Infra: Delete image in branch remove workflow

[Haarolean]

Need to remove the image from the registry as well in .github/workflows/branch-remove.yml

Hi @Haarolean, do you have any idea on how you would do this?
I don't see any easy way to remove an image from a registry (though I don't really know AWS registry). In some case (like on gitlab) one should remove all tags and a scheduled background job delete old images.
