PackageTests involving python deadlock in Windows CI

[jasagredo]

As it can be seen here https://github.com/haskell/cabal/actions/runs/10102223563/job/27937411023?pr=10225, some tests (I suspect both that involve python, i.e. the RejectFutureIndexStates and UpdateIndexState) are deadlocking on Windows on CI. This doesn't happen locally on my machine.

This issue is open to investigate such tests on Windows CI.

Would be fixed with #9540 if that was finished, probably.
