Please describe the issue that you are experiencing

This issue is a reprise of #1059. Now that PEP 639 is provisionally accepted, the coherent system has implemented support, and subsequently packages built under that system fail with the error:

 coherent.deps main 🐚 twine upload dist/*
Uploading distributions to https://upload.pypi.org/legacy/
ERROR    InvalidDistribution: Metadata is missing required fields: Name, Version.                                                                  
         Make sure the distribution includes the files where those fields are specified, and is using a supported Metadata-Version: 1.0, 1.1, 1.2, 
         2.0, 2.1, 2.2, 2.3.             

The error message "missing required fields" appears to be incorrect. The fields are there.

According to the spec tools should warn (but presumably not error) if the version is a minor increment higher than the highest supported.

Please list the steps required to reproduce this behaviour

1. git clone https://github.com/coherent-oss/coherent.deps; cd coherent.deps
2. pipx run coherent.cli build
3. pipx run twine upload dist/*

Anything else you'd like to mention?

Relevant is this comment about supporting pkg_info>=1.11, which seems to address this issue.

[jaraco]

Twine is pinned against pkg_info 1.11, so is hard-blocked against supporting this new metadata version. #1123 proposes to unblock it, but that PR has languished.
