Let's wait for an official release of pyproject-metadata

It doesn't seem one is coming. Last one was 13 months ago, and people that can release don't seem to even respond for the calls to do a release for 2+ months already. I did not review earlier conversations, so it likely have been longer than that.

something seems to be happening afterall: pypa/pyproject-metadata#84 (comment)

It is superseded by #228, thanks.
