[stable-2.16] release.py - Add missing setuptools arg to prepare (#83887) (#83889)

* release.py - Add missing setuptools arg to prepare

This allows the prepare command to accept the `--no-setuptools` argument.

It also fixes a traceback when using the `prepare` command.

* Use a more accurate type hint
