feat: Use hatch envs instead of nox

[kratsg]

This PR migrates from nox to hatch env updating the following files initially created by scikit-hep/cookie:

• .github/CONTRIBUTING.md
• .github/workflows/ci.yml
• pyproject.toml

Two particular notes:

• chose not to put pre-commit in the hatch env, although I certainly could have done so, it feels like pre-commit belongs outside of the package fundamentally
• chose to define matrix of python versions in hatch env for the pytest to keep the equivalent functionality that nox had (as best as I could) -- but this does come with the minor caveat that one needs to keep the version consistent between the matrices in .github/workflows/ci.yml and pyproject.toml as I use hatch run +py=${{ matrix.python-version}} dev:test to pick out the version to run.

We can't use --strict just yet as we're blocked by incompatibility between two projects, see timvink/mkdocs-git-revision-date-localized-plugin#101 for details.

@henryiii - this PR represents transitioning from noxfile.py to hatch env fully.
