setup.py install is deprecated

[intgr]

Will need to deal with this at one point. https://blog.ganssle.io/articles/2021/10/setup-py-deprecated.html

This warning shows up when making a release:

.../site-packages/setuptools/_distutils/cmd.py:66: SetuptoolsDeprecationWarning: setup.py install is deprecated.
!!

        ********************************************************************************
        Please avoid running ``setup.py`` directly.
        Instead, use pypa/build, pypa/installer or other
        standards-based tools.

        See https://blog.ganssle.io/articles/2021/10/setup-py-deprecated.html for details.

I can go back to #1570 if needed :)

Full-on pyproject.toml usage is one solution.

Seems like this warning will also be silenced by a smaller change in scripts/release.sh

-python setup.py sdist bdist_wheel
+python -m build
