ci: windows onedir and onefile tests don’t fail if they should

[robin-nitrokey]

We run a series of commands in cd-windows.yaml and expect that the step fails if any of the command fails:

pynitrokey/.github/workflows/cd-windows.yaml

Lines 59 to 63 in 8ed9274

	run: |
	dist/nitropy/nitropy.exe --help
	dist/nitropy/nitropy.exe version
	dist/nitropy/nitropy.exe nethsm --host nethsmdemo.nitrokey.com state
	dist/nitropy/nitropy.exe list

But if the nethsm command fails, this step still succeeds, see for example:

https://github.com/Nitrokey/pynitrokey/actions/runs/23602605516/job/68736514345

Possible causes:

• We don’t set the exit code correctly on Windows.
• The Windows runner ignores the failure.

The same code works as expected on Linux:

pynitrokey/.github/workflows/cd-linux.yaml

Lines 56 to 60 in 8ed9274

	run: |
	dist/nitropy --help
	dist/nitropy version
	dist/nitropy nethsm --host nethsmdemo.nitrokey.com state
	dist/nitropy list
