Next helix test move

[marcpopMSFT]

Reduce the helix move to a single test group to limit the impact in the build and see if the main set of changes can get in.

@dsplaisted @gkulin I was seeing workload manifest mismatches (between mono and emsdk) in this PR. Digging through the log files, one of Grace's manifest update tests ran just before a failure regarding a mismatched manifest (though our log files didn't capture enough info for me to confirm that it was updating the manifests of the dotnet used in the later test). Once I disabled Grace's tests, the PR passed.

I'm inclined to file a bug to have Grace review those 3 tests I disabled to figure out why they are impacting other tests and merge this PR (and keep going with the helix migrations). Thoughts?

Yes, that sounds right. Probably those tests are modifying state that we didn't expect them to (ie modifying the workloads that are installed in stage 2).

I'm going to update the reporoot per Daniel's feedback and add a link to #25175 in the skip comment before merging.
