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
• Closes Remove dependency files and add dependencies to setup.py #3463

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.

@vladvildanov Rebased. I'll fix the tests if there's any interest in this.

Could you add "closes #3463 "?

Btw: the tests failing in

FAILED tests/test_asyncio/test_commands.py::TestRedisCommands::test_client_setinfo[single] - AssertionError: assert '5.3.0b5' == '5.2.1'
    
    - 5.2.1
    + 5.3.0b5

is very curious – given the string "5.3.0b5" does not appear in the source here at all, it almost looks like the CI pipeline is installing an entirely different version of the package...

and indeed:

  Downloading redis-5.3.0b5-py3-none-any.whl (271 kB)

IOW, the CI pipeline seems to be confused about which libraries it's using...
