Forgejo appears to immediately delete registry content that is
overwritten. This means that we are forced to delete our previous
workaround of making a temporary tag and use a new, more absurd
workaround of making an entire temporary image that we basically only
need to create to get its hash.
However, on the plus side, the new workaround doesn't create garbage
tags to begin with, which means that we don't have to deal with GitHub
not implementing the standardized tag delete endpoint and instead
only implementing a proprietary one.

If we don't want to have separate registry tags by architecture (EWWWW),
we need to be able to build multiarch docker images. This is pretty
simple, and just requires making a manifest pointing to each of the
component images.
I was *going* to just do this API prodding with manifest-tool, but it
doesn't support putting metadata on the outer manifest, which is
actually kind of a problem because it then doesn't render the metadata
on github. So I guess we get a simple little containers API
implementation that is 90% auth code.
