Description of change

• Refs Use setuptools setup.cfg declarative configuration #1316
• Refs Fixing the package to include commands #1649
• ♻️ Remake of Switch to PEP 517 packaging using hatchling #2388, a year later
  *❗Contains dependency changes from Partial clean up of Python 3.7 compatibility #2928

Quoting the description from #2388, a year later...

This PR shifts redis-py from legacy setup.py packaging to PEP 517 compliant packaging using hatchling from PyPA.

Essentially, this does what was discussed in #1658 but with the increasingly standard hatchling tool instead of poetry's idiosyncracies.

As with #2388, python -m build does create a working wheel with all modules included.
