confirm if kubeapps is to be installed on SS or WL cluster

[KeithRichardLee]

Bonus lab has title of "Deploy Kubeapps to Shared Services Cluster" but the steps deploy to the workload cluster https://github.com/Tanzu-Solutions-Engineering/tkg-lab/blob/main/docs/bonus-labs/kubeapps.md

Confirm target cluster and update tkg-lab docs (note, may also impact e2e docs)

[doddatpivotal]

It should be workload cluster. Corrected here and at https://github.com/doddatpivotal/tkg-lab-e2e-adaptation/blob/main/docs/00-tkg-lab-foundation.md
