CI: release: Change for calling setup.py directly to using build

Calling setup.py directly is depreciated, this switches to using pypa's build tool for wheel and sdist building.

See https://blog.ganssle.io/articles/2021/10/setup-py-deprecated.html for reasoning and https://pypa-build.readthedocs.io/en/stable/ for build documentation.
