I originally just wanted to remove the py38 env from tox but then (as it usually happens 😆 ) I noticed the pytz, jinja and setuptools envs. They all install the same dev extra meaning we run the same test suite multiple times, one for each env.

The envs actually used to install the respective packages (pytz, jinja and setuptools ) until #1159 which removed it. I don't think we need to fully restore this behaviour, probably one env with the optional dependencies and one without is enough, which is what I've done here.

I also took the liberty to switch to dependency groups since there was the TODO in pyproject.toml and it just felt natural here. There are now two groups:

• test: installs only what is needed for the tests
• dev: installs the extras (pytz, etc..)

Tox runs the dev group on all versions + runs the bare test group on py314 only.

Feedback welcome! :)
