NEP29 Compliance

[bjlittle]

This PR adopts the NEP29 Drop Schedule for minimum supported versions of python and numpy.

When working on #84 I noticed that the PyPI versions were wrong for pytest-pyvista. Turns out, incorrect syntax (probably migrated from setup.py or setup.cfg) was used to specify the required python version for the package; minor fix sorted this.

Went the extra mile and also configured the validate-pyproject pre-commit hook to automate continued confidence in the pyproject.toml.

Thanks! I wondered the same thing. About adding validate-pyproject, also need to ask the @MatthewFlamm if it would be useful to add as it would increase run time. If it is adopted here, please consider sending an additional PR to pyvista/pyvista too.

@tkoyama010 Cool, thanks.

Although, it seems to be a relatively snappy pre-commit hook. I'm not seeing much difference in runtime or resources being used.

Since this package is required for testing pyvista, we can't drop python 3.8 support without dropping it in PyVista. We should probably move the discussion there.

[tkoyama010]

Oh, I see. I totally forgot this project was used in PyVista😅.

[tkoyama010]

I started pyvista/pyvista#4960 . Let's discuss it there!

[tkoyama010]

Keep this while we discuss it.

Whilst we await a decision on this one, I'm going to put the pull-request into draft to ensure it's not merged 👍
