Lint: Black -> Ruff formatter

[ogajduse]

Problem Statement

#14781 attempts to upgrade some of our pre-commit hooks including black. The new version of black formats 150+ files. Given the patch size, I propose switching to Ruff formatter as the patch size is comparable to the patch for the new version of black.

Reason to switch to Ruff

(copy&paste from one of the comments in this PR)
Astral's page sums it up pretty well. astral.sh/blog/the-ruff-formatter

I would like us to switch to Ruff mainly because of its speed compared to black. It is incredibly fast and the compatibility with Black is 99%. Looking at the patch, it might not look like 99%, but taking into account how big our project is and what changes were made, it is not that bad.

Solution

• Remove the black formatter and substitute it with Ruff formatter,
• bump the version of ruff pre-commit hook.

A couple of small, non-blocking suggestions, but looks good to me overall.

ACK. Merge pending Danny's recommendations

I think this is OK but is there some specific reason for us to prefer Ruff?

@ogajduse Could we run some tests before merge it ? Especially the code where reviewers commented/discussed concerns ?

Sure we can! I do not really see a need to do so, but @Gauravtalreja1 and/or @shweta83, feel free to trigger PRT here.

AFAIR, In history, we have broken the sanity when we merged a large formatting PR, So I see the need here.
