If several jobs in the windows-test or vs-test matrices fail, the
upload-artifact action in each job tries to upload the test directories
of the failed tests as "failed-tests-windows.zip", which fails for all
jobs except the one which finishes first with the following error:
Error: Failed to CreateArtifact: Received non-retryable error:
Failed request: (409) Conflict: an artifact with this name
already exists on the workflow run
Make the artifacts name unique by using the 'matrix.nr' token, and
disambiguate the vs-test artifacts from the windows-test ones.
