GHA/windows: mark 3023, 3024 flaky for mingw-w64 7.3.0 job

They became flaky recently as reported by Testclutch and firsthand
observations. It's curious because it only seems to happen in 7.3.0,
but not in the very similar (except non-Unicode) 9.5.0 job.

We've found no explanation or reason for them so far.
