Update Pylint dependency to 4.0+

[mhucka]

This simply does the minimum to update the version of Pylint to 4.0.x.

Code Review

This pull request upgrades Pylint to version 4.0 and Astroid to version 4.0, updating the .pylintrc configuration accordingly. It also cleans up various environment requirement files by removing legacy compatibility packages (such as tomli, exceptiongroup, and importlib-metadata) and unifying the cirq-core dependency. A review comment suggests updating an outdated comment in .pylintrc regarding the renamed extension-pkg-allow-list option.

It looks like this will change the minimum python version for the developers to 3.11, while 3.10 is still supported for users. Is this discrepancy fine? I guess we are not actually testing with 3.10 in the CI anyways, so maybe this is fine.

Sorry, where does it change the minimum Python version? Pylint 4.0.x is supposed to be compatible with 3.10, and I don't see a change elsewhere that would require 3.11.

The removed lines from the env files remove conditional dependencies for python < 3.11 (e.g. here), such as older versions of Cirq.

When running pip install -r dev_tools/requirements/envs/dev.env.txt using python 3.10.20 I get: ERROR: No matching distribution found for cirq-core==1.6.1.

If it wasn't pylint, maybe uv is using the current python version as the minimum when generating the env files?

Oh, argh, I missed that in the diff. It's probably due to how uv is getting run by the script. I'll check it.

Update: yes, uv needs to be given an option to tell it what Python version to target. I must have run the script in 3.11 when I did this PR, not realizing it. On the plus side, we just found an important fix to make to create-env-files.sh. I'll do a separate PR for that.

Update: regenerated corrected environment files.

Thanks again for catching that. I am once again reminded why it's good to have human reviewers :-).

LGTM. Thanks for fixing the uv outputs!
