Run unit tests on Windows

• Currently, running unit tests on Windows is not part of our CI pipeline
• This causes issues like getMemoryInfo always returning a placeholder value to go unnoticed (see Get rid of dependency on deprecated WMIC on Windows #2771 (comment))

I am afraid this will have a pretty negative effect on the CI, windows in CI is terribly slow and flaky, so if we are to do this, I would at least keep the checks optional.

I mean, we already run tests on windows in crawlee-python. You are right that they are like 50-100% slower than on Linux, but we live with that.

I thought we still ran tests on windows, just not required for PRs to be merged (as windows has been consistently unstable) 👀
