Fix: Revert release.yaml Python build to TOX

Reverts a change originally made in:
https://gerrit.linuxfoundation.org/infra/c/releng/lftools/+/73482

The new python-build-action has some unresolved issues when Python
versioning is set to dynamic. Until those are addressed, we are
blocked on tagging/releasing lftools.
