fix(ci): build pypi release via `uv build` instead of removed setup.py (

#3700) [skip ci]

The pyproject migration removed setup.py, so the publish workflow failed at
`python setup.py sdist` (No such file). Build the sdist+wheel with `uv build`
(PEP 517; setuptools backend reads the version from VERSION). Also make the
GitHub release step idempotent so a re-run/re-tag of an existing release
doesn't fail, and drop the unused dependency-install step.
