Remove wacklig upload from GHA workflows
Remove wacklig upload from GHA workflows

We added the "on-pr" upload with the intention of figuring out if there
are tests that are only flaky on windows, but that didn't really work
out. We cannot easily tell if PRs failed because they were still work in
progress or because the tests are really flaky. This makes the wacklig
dashboard overall less useful - so this commit reverts the upload.

To accomplish the original goal we'd instead need to add another
periodic test run on windows that runs against the master branch.
