binding/python: Enable ruff for lint and format

[Xuanwo]

          It's time for us to introduce a python formatter. How about using ruff?

I think black should be better， because it is the most popular code formatter in the Python ecosystem

BTW，we should also import isort as import formatter （lol

[Xuanwo]

I think ruff is the trend. And we love tools written by rust🦀

Ruff can replace black, isort, xxx and it's fast.

+1 for ruff, one-stop toolkit (like cargo) provides better developer UX.

It seems Ruff added the black compatible mode recently. (https://astral.sh/blog/the-ruff-formatter)
And isort is also available. (https://docs.astral.sh/ruff/settings/#isort)

I would like to help investigate adding this infra.

@codeworm96 Hello, would you mind to share if there is any update for this PR?

[codeworm96]

Sure. I would like to share my current plan for discussion before submitting the PRs:

1. we need to add ruff (and ruff confs) to the project: It seems currently dev dependencies as organized as optional-dependencies, like benchmark, docs, tests. I think we can add a new lint category for ruff.
2. I tested the current code, it did not pass the lint by default. So some code change and/or suppressing some rules are needed.
3. document lint & format commands
4. As the final step, I think we should add lint as part of the CI tests once we fix the lint. But I do not have a detailed idea yet.

Hi @codeworm96, are you still on this issue? Can I offer some assistance?
