Probing Apache Superset with Python 3.12.

Hi @villebro,

may I humbly ask you if you have any idea why this job, that aims to start using Python 3.12 on the test matrix, fails on CI/GHA with ModuleNotFoundError: No module named 'distutils' ¹? Is it something related to our CI setup, or is Apache Superset not compatible with Python 3.12 yet?

With kind regards,
Andreas.

Apparently, the job is failing when trying to install NumPy 1.23.5, which does not install well on Python 3.12.

Collecting numpy==1.23.5 (from apache-superset==3.*)

  Caused by: distutils was removed from the standard library in Python 3.12. Consider adding a constraint (like `numpy >1.23.5`) to avoid building a version of numpy that depends on distutils.

We have been able to dig out the corresponding ticket.

NumPy 1.26 is available for Python 3.12, so maybe upgrading to that version from NumPy 1.23 might be feasible, because it's not too different?
