validation port forwards to pod not svc

[willr3]

I was manually running the bash commands from the validate_model and I think there is an inconsistency in Wait for the model to answer successfully

https://github.com/openshift-psap/topsail/blob/main/projects/kserve/roles/kserve_validate_model/tasks/validate_model.yaml#L46

This appears to be exposing a port that exists on the pod but the port forwarding is targeting the svc. I do not see an existing variable for the pod name but I believe the line should be

      oc port-forward po/{{ pod_name_goes_here }}-predictor 8080:8033 -n {{ kserve_validate_model_namespace }} &
