CI/DOC: Enforce ES01 in CI

[jordan-d-murphy]

Enforce ES01 in CI so that it can be fixed and enforced in chunks like other docstring errors.

The added functions come from the result of running scripts/validate_docstrings.py --format=actions --errors=ES01

Part of our ongoing work to continue enforcing numpydoc validations: https://numpydoc.readthedocs.io/en/latest/validation.html#built-in-validation-checks

• xref CI/DOC: Enforce PR02 in CI #56971
• Tests added and passed if fixing a bug or adding a new feature
• All code checks passed.
• Added type annotations to new arguments/methods/functions.
• Added an entry in the latest doc/source/whatsnew/vX.X.X.rst file if fixing a bug or adding a new feature.

pre-commit.ci autofix

@mroeschke the merge conflicts in code_checks have been resolved

Just of warning, more maintainers may decide some of these numpydoc rules are not worth enforcing, but for now OK to include

Thanks @jordan-d-murphy

[jordan-d-murphy]

okay - thanks for the heads up. Always happy to adjust and redirect effort elsewhere as needed. I certainly appreciate the speedy reviews and helpful suggestions!

In the end it's open source and any contribution of yours is welcome :)

Personally I find fixing the docs to enforce these rules is a bit more externally useful than enforcing some of the missing rules in the CI (since pandas doesn't not add new APIs with docs often anymore)
