Question-Answering incorrect service name

[fideltak]

Description & Reproduction

First of all, thank you for great demo contents.
In new UA 1.3, Kserve creates service like service/vectorstore-predictor.

vectorstore-predictor                 ExternalName   <none>           istio-ingressgateway.istio-system.svc.cluster.local   80/TCP                                               11m
vectorstore-predictor-00001           ClusterIP      10.97.188.94     <none>                                                80/TCP,443/TCP                                       11m
vectorstore-predictor-00001-private   ClusterIP      10.101.254.37    <none>                                                80/TCP,443/TCP,9090/TCP,9091/TCP,8022/TCP,8012/TCP   11m

However jupyter notebook is described as vectorstore-predictor-default.
And transformer code is hardcoded as {deployment_name}-predictor-default.

It seems -default prefix has been removed from kserve spec.
kserve/kserve#1397

Expected behavior

• Corrent service path in Jupyter Notebook
• Correct service path in codes
  • Or change app architecture to enable to set service path by env values.
