Mark test_posix_proxy_sockets to depend on multithreading

Mark test_posix_proxy_sockets to depend on multithreading to skip it in old non-SAB capable browsers.

Ruff is failing on organize imports, and doesn't tell me what I should do. When I run ruff locally, it says all checks passed. @sbc100 would you have a gospel ruff installed to give a diff?

Yes, but if you are unable to using requirements-dev.txt we should figure out a solution to that. Can you try using pip to install into a sub-directory and then running ./my-local-pip-install/bin/ruff?

TBH, I often add just do pip3 install -r requirements-dev.txt --break-system-packages but I guess that adding --break-system-packages might seem scary.

The alternative is to run pip3 with --target ./my-local-pip-install or use a python virtualenv (which basically does the same thing).

The issue is not that I would not be able to install ruff, but the issue is that it does not report any problem with the code.

I am not scared to add --break-system-packages.

After pip3 install requirements-dev.txt, ruff --version gives 0.14.1, but ruff check says All checks passed!.
