[CI] Investigate and fix occasional test failure with Node v22 on Windows image

[RandomByte]

In our CI we regularly see tests failing specifically with Node v22 on Windows 2025 image. Retrying the tests usually resolves the issue immediately

Example run: https://github.com/SAP/ui5-linter/actions/runs/15703035505/job/44242248893?pr=700

530 tests passed
6 tests skipped
Error: Process completed with exit code 1.

All the tests are passing, however the exit code is set to 1.

I suspect it has something to do with asynchronous tests that are not fully waited for but not sure.

With any other image, all of the tests (606 total) run through and pass.
However with "Node22, windows2025" only 530 run through.

So, not all tests are passing, but you might be right that they're just not being waited for.

Great observation. I guess next we should check which ones are the missing tests

[maxreichmann]

Just fyi, sometimes it's also Node23 (as in this run: https://github.com/UI5/linter/actions/runs/15846199709/attempts/1).
Depending on whether we deprecate Node23 in our jobs, this might be not relevant.

The same behavior can be observed also with "Node24, windows2025"

Note that #728 did not resolve the issue

Fixed through #768
