chore(ci): Add Windows test job

[effigies]

No idea how tied we are to posix. Probably pretty tightly, but there's no reason in principle it couldn't be undone.

xref #1111

[effigies]

Looks like actually a fairly manageable job. @kaare-mikkelsen, would you be interested in having a go at adding Windows support?

[kaare-mikkelsen]

Hi @effigies
Well, yes and no :) I would like it to happen, and am not averse to contributing to a good tool. But I would probably also have to learn a bit more about how to contribute to pybids, and would have to find the time. I doubt that I will have much opportunity until end of january (I'm heading into exams season, and am presently buried in reports that need grading).
It sounded like you already looked at what would likely need to be done. Can you add a few pointers here?

@kaare-mikkelsen

My approach at this would be to first fix the failing tests from this run: https://github.com/bids-standard/pybids/actions/runs/12323508594/job/34399274262?pr=1113

I would :

• fork the pybids repo
• clone your fork
• install tox (see the readme)
• pick one test that fails in CI:
  • let's say src/bids/layout/tests/test_path_building.py::test_path_building_in_raw_scope
• Make sure the test fails locally using :
  • tox run -e full -- src/bids/layout/tests/test_path_building.py::test_path_building_in_raw_scope
• update the pybids code to make the test pass (the failing test should print the stack trace of the failure so it should leave a lot of breadcrumbs to find where to start looking at).

@Remi-Gau that sounds pretty straight forward :) I will look into this when I get the time again, but also won't be in any way upset if someone solves it before then.
