Hi Guix!

I think it's a time to review and merge python-team branch.

It will bring refactored pyproject-build-system, refreshed collection of
packages from python-build module, refreshed python-numpy (1.24),
default python-pytest (8+), fresh python-flask, some clean up from
python-nose which is deprecated for few years.

Please test and report for any issues of the package you
love/need/demand.
