[TSV][Bug] Fix the missing configuration for current repo so it won't block normal customers

SDK team is trying to add missing `tspconfig.yaml` for `workloads/Workloads.SAPVirtualInstance.Management` in our April release but we found the tsv checked all 4 libs under the same `workloads` folder. Since other 3 haven't have language configurations yet so we failed with [TypeSpec Validation and the log is here](https://github.com/Azure/azure-rest-api-specs/actions/runs/14638819466/job/41076137512#logs).

- [pr link](https://github.com/Azure/azure-rest-api-specs/pull/33826)


I think ultimately all spec should have configs but for now spec repos have some missing configurations libs, Could eng team have one-time fix for them?

Otherwise pr authors will be blocked by failures that is un-relevant to current services. Also I am curious why we include all libs under the same RP, any reasons to do that?

Start with workloads/Workloads.SAPVirtualInstance.Management/tspconfig.yaml and the TypeSpec Validation log from the linked workflow run; compare the four libraries under workloads and the related pull request. Done means the April-release configuration can be validated without unrelated libraries lacking language configurations blocking the change.
