Bump pipdeptree

[oz123]

This is required for enabling Python3.11

Perhaps add the changes from #5245 so that we are assured that the tests pass.

I prefer doing this in a separate PR. Let's merge this one, and then one can merge the main branch to #5245 .

After this was merged, I rebased the Python 3.11 tests in #5245 and they fail. :-(

Same failures?

It appears that the vendored-in pytest is trying to import tomli instead of using the tomllib that is built into Py3.11. https://docs.python.org/3.11/library/tomllib.html

Is the vendored-in pytest current? https://github.com/pytest-dev/pytest/releases

lib/python3.11/site-packages/_pytest/config/findpaths.py",
  line 67, in load_config_dict_from_file
    import tomli
ModuleNotFoundError: No module named 'tomli'

This will need to wait until pytest v7.2.0
