Use apps/v1 ReplicaSet in controller and tests.
This updates the RS/RC controller and RS integration/e2e tests to use apps/v1 ReplicaSet, as part of #55714.
It does *not* update the Deployment controller, nor its integration/e2e tests, to use apps/v1 ReplicaSet. That will be done in a separate PR (#61419) because Deployment has many more tendrils embedded throughout the system.
```release-note
Conformance: ReplicaSet must be supported in the `apps/v1` version.
```
