I tried to upgrade Python to 3.12 but then pip install fails with:

[INFO] Installing environment for https://github.com/psf/black.

  note: This error originates from a subprocess, and is likely not a problem with pip.

Which is weird. I wonder why it would fail for Python 3.12 but not Python 3.10.

We can do it in a separate PR though.
