NEP 29 update

[mattwthompson]

On April 14, 2023 (this Friday), NEP 29 drops Python 3.8

https://numpy.org/neps/nep-0029-deprecation_policy.html

Support for Python 3.11 is blocked by upstream packaging (openforcefield/openff-interchange#645)

I couldn't find anything else in the tooling after some agressive searching:

$ grep -r "3\.8" . --exclude="*.svg" --exclude="*.pdb" --exclude="*.ipynb" --exclude="*.sdf" --exclude="*frcmod*" --exclude="*inpcrd*" --exclude="*.mol2"
