Build under Windows is flaky and PNPM frequently fails (OSOE-959)

[Piedone]

The CI build under Windows, but not under Ubuntu, frequently fails with the following error:

Starting to execute tests from the C:\a\Open-Source-Orchard-Core-Extensions\Open-Source-Orchard-Core-Extensions\test\Lombiq.UITestingToolbox\Lombiq.Tests.UI.Samples\Lombiq.Tests.UI.Samples.csproj project.
Starting testing with `dotnet test --configuration Debug --nologo --logger 'trx;LogFileName=test-results.trx' --logger 'console;verbosity=detailed' --verbosity quiet  --filter 'FullyQualifiedName!~SecurityScanningTests&FullyQualifiedName!~BehaviorElasticsearchTests'  C:\a\Open-Source-Orchard-Core-Extensions\Open-Source-Orchard-Core-Extensions\test\Lombiq.UITestingToolbox\Lombiq.Tests.UI.Samples\Lombiq.Tests.UI.Samples.csproj`.

This needs to be investigated with a more verbose log.

When rebuilding the whole solution from VS locally, the following can happen:

48>> SRC=$(node scripts/get-path js source) DEST=$(node scripts/get-path js target) && if-env SRC=! && echo "Skipping scripts" && exit 0 || node scripts/compile-scripts "$SRC" "$DEST" "${INIT_CWD}/config/" || AREA=scripts STEP=compilation pnpm error
