Add instructions for configuring linting in the Python documentation …

…using Ruff extension (#14896)

Added documentation for #14198

I also suggest replacing format guides from `black` to `ruff` to unify
the tooling in the document.

Ruff is now widely used in the Python community, including
[fastapi](https://github.com/tiangolo/fastapi/blob/cd6e9db0653eabbf0fb14908c73939a11a131058/pyproject.toml#L213).
It's compatible with black but a lot faster.
