v1.12.4

Be nice to FOSS maintainers.

✨ What's Changed

The main theme of this patch release that the support for uploading PEP 639 licensing metadata to PyPI has been fixed in #327.

🛠️ Internal Updates

A few smaller updates include the attestation existence being checked earlier in the process now, listing all the violating files together, not just one (PR #315).
And the lock file with the software available in runtime has been re-pinned in #329.
Additionally, the CI now runs the smoke-tests against both Ubuntu 22.04 and 24.04 explicitly via da900af.
