Testing on Windows

[kaczmarczyck]

The tool is currently used mainly on Linux and MacOS. We need to run all features on Windows to make sure it works.

Why don't you also run some test on Windows through github workflows?
And you can even have a scheduled workflow to make a nightly build on all supported OSes every night.

First finding: Bazel's stamping doesn't work on Windows.

A workaround to disable this feature (you have to manually change your report to contain the commit):
