Code LGTM.
Adding hold in case if you want to do additional testing prior to merge or have someone else take a peek at code as well. Otherwise feel free to unhold.

I encounter the below error when running the integration test, which only happens without PVC.

cannot wait for workspace start: "workspace instance 1c7a2072-0461-49ae-964e-51d1d0302362 failed: cannot initialize workspace: cannot initialize workspace: git initializer clone: git ls-remote --exit-code origin main failed (exit status 2): "

I believe it's because we use the gitpod-io/empty repo for testing, and running this command locally failed with exit status 2 as well.

$ git ls-remote --exit-code origin main
