      Description of problem:

      Cannot Pull Image When using ImageStream name in DeploymentConfig as image value, the actual image in the Pod gets resolved to docker.io instead of internal registry.

      Version-Release number of selected component (if applicable):

          OCP 4.12

      How reproducible:

          Always

      Steps to Reproduce:

          1. Deploy an ImageStream pointing to an existing image in internal mirror registry
      
      ~~~
      apiVersion: image.openshift.io/v1
      kind: ImageStream
      metadata:
        name: oraclelinux
        namespace: default
      spec:
        lookupPolicy:
          local: true
        tags:
        - annotations: null
          from:
            kind: DockerImage
            name: <internal_mirrorresgistry>/os/oraclelinux:9
          generation: 20
          importPolicy:
            importMode: Legacy
          name: "9"
          referencePolicy:
            type: Source
      ~~~
      
       2. Deploy a DeploymentConfig pointing to the IS from step 1
      
      ~~~
      oc -n default create deploy oraclelinux --image=oraclelinux:9 
      ~~~
      
      3. Resulting pod fails with ImagePull error. oraclelinux:9 image pull is failing, the cluster will behave as if it is pulling these images from DockerHub (docker.io), which is not where the images are stored.
      .    
      
      ~~~
      Failed to pull image "oraclelinux:9": reading manifest latest in docker.io/library/$IMAGESTREAM_NAME: requested access to the resource is denied
      ~~~ 

      Actual results:

      ~~~
      requested access to the resource is denied
      ~~~ 

      Expected results:

      Pod pulls the image referenced by ImageStream from internal registry
