What does this PR do?:

Pick Model Name from the Annotated Catalog Resource provided by the Bridge

This was required as Models outside RHOAI Model Catalog didnt necessarily have the model name set as metadata.name. Model Catalog Bridge now sets the annotation for the model name:

Model Resource deployed outside RHOAI Model Catalog

apiVersion: backstage.io/v1beta1
kind: Resource
metadata:
  namespace: default
  annotations:
    backstage.io/managed-by-location: ModelCatalogResourceEntityProvider:development
    backstage.io/managed-by-origin-location: ModelCatalogResourceEntityProvider:development
    rhdh.modelcatalog.io/model-name: qwen3-8b-fp8
  name: vllm-qwen3-8b-fp8
