Apply some ruff rules

[cclauss]

Some optimizations for performance or readability.

I do not understand DeepSource's complaints that two functions have increased cyclomatic complexity when both ruff and flake8 agree that the cyclomatic complexity of these functions is unchanged.

% ruff check --select=C901 # Results are the same on main and this branch.

isort/identify.py:43:5: C901 `imports` is too complex (33 > 10)
isort/settings.py:827:5: C901 `_get_config_data` is too complex (27 > 10)

@staticdev What do you think of adding ruff to the linters? I don't really like making changes based on a linters output but then not adding the linter to CI to ensure the changes don't creep back in.

I don't see a problem we can add ruff linter.

It seems strange to apply ruff rules to a project that is not configured to follow ruff rules.

On a personal note, I view ruff as harmful to the Python ecosystem, as its paid developers cannibalize cumulative decades of others' work in a language that Python developers may not know how to contribute in. It's particularly galling that their homepage prominently features a quote from Timothy Crosley, who started and effectively abandoned isort itself sometime after ruff copied the project under a config option blatantly named isort.

Anyway, I've left feedback on the PR. ruff introduced what appears to be an equivalently-unnecessary !s in several f-strings that I suggest addressing.

@kurtmckee I am contributing also to open-source software since before Github exists, I feel you and share partly your opinion. But I have a long disclaimer, even being maintainer for isort, I am using ruff in many of my projects. I respect the diversity and competition of the projects and want them to thrive with isort, or ruff, or the next cool tool. This for me is kinda the beauty of open-source.

Ruff is definetely fast but also feels immature and incomplete now. Astral for me is doing a good service, but needs some years maybe to catchup with all ambitious projects.

Tldr: i think isort and ruff can coexist in piece. And we should make them help developers have a better life.

This code change looks good to me.

[cclauss]

I do not have merge rights so a maintainer would need to approve and merge.

Should I add ruff to CI in this PR or in a separate PR?

[kurtmckee]

(By the way, @cclauss and @staticdev, I sometimes see you both pop up in other repos I interact with -- thanks for the work you both do!)

[staticdev]

Thanks @cclauss, I think this will improve our code readability. LGTM.
Thanks also @kurtmckee for the review.

@DanielNoord also good for you?

@cclauss I think this one already have a nice size. I would advice doing it in another one.
