Change to pwsh on windows runner breaks file option

[niklasstich]

It appears that #188 has broken the file option on windows runners. Our Pipeline runs broke around the same time that pull request was merged.

Run pinned to @v2 (after #188 was merged): https://github.com/ProjektAdLer/Autorentool/actions/runs/6123453733/job/16621372161
Run pinned to commit 95b1a23: https://github.com/ProjektAdLer/Autorentool/actions/runs/6123557884/job/16621699824

As you can see, the other tasks running our test suite run without failure and pinning the version of the github-action back to the commit before #188 fixes the run.

If you need any other information for replication please let me know.

@niklasstich thanks for the report, and the details on your current workaround.

I have shared this with an engineer and will ask them to TB with you here on it.
