[Feature] Add validation for numpydoc

[K-Meech]

Is your feature request related to a problem? Please describe.
Currently, there are no checks for docstring style, meaning it is easy to introduce styles like reST erroneously.

Describe the solution you'd like
We could add validation of numpydoc via precommit with a pre-commit hook. Individual rules can be easily ignored in the pyproject.toml like so

[tool.numpydoc_validation]
checks = [
    "all",   # report on all checks, except the below
    "EX01",
    "SA01",
    "ES01",
]
