Fix broken statefulset e2e test

**What this PR does / why we need it**:

Fixes the CockroachDB statefulset e2e test.

This was broken back in #43637 when the logic in
`(*StatefulSetTester).CreateStatefulSet` switched from using
`generated.ReadOrDie` to read the entire service.yaml file and pass it
to kubectl to using `manifest.SvcFromManifest`, which assumes that the
file contains only a single service.

To fix the test, just remove the second service, which isn't needed to test the Statefulset functionality.

**Which issue this PR fixes**:

Fixes #52750
