When used in heads-only mode, oc-mirror does not record the operator bundles minimum version if a target name is set.

The record values ensures that bundles that still exist in the catalog are included as part of the generated catalog and that the associated images are not pruned. This behavior will prune bundles that have when no minimum version is set in the imageset configuration and the bundles still exist in the source catalog.

Using the advanced cluster management package as an example.

1. Find the latest bundle for acm in the release-2.6 channel with oc-mirror list operators --catalog registry.redhat.io/redhat/redhat-operator-index:v4.10-1663021232 --package advanced-cluster-management
2. Create an mirror set configuration to mirror an operator from an older catalog version

apiVersion: mirror.openshift.io/v1alpha2
kind: ImageSetConfiguration
storageConfig:
  local:
    path: test
mirror:
  operators:
    - catalog: registry.redhat.io/redhat/redhat-operator-index:v4.10-1663021232
      targetName: test
      targetTag: test
      packages:
        - name: advanced-cluster-management
          channels:
            - name: release-2.6


2. Run oc-mirror --config config-with-operators.yaml file://
3. Check the bundle minimum version on the metadata using oc-mirror describe mirror_seq1_000000.tar under the field operators, the advanced-cluster-management should show version found in Step 1.
4. Create another ImageSetConfiguration for a later version of the catalog
apiVersion: mirror.openshift.io/v1alpha2
kind: ImageSetConfiguration
storageConfig:
  local:
    path: test 
mirror:
  operators:
    - catalog: registry.redhat.io/redhat/redhat-operator-index:v4.10
      targetName: test
      targetTag: test
      packages:
        - name: advanced-cluster-management
          channels:
            - name: release-2.6
4. Check the bundle minimum version on the metadata using oc-mirror describe mirror_seq2_000000.tar under the operators field. 

The catalog entry in the metadata shows packages as null.

It should have the advanced-cluster-managament package with the original minimum version or an updated minimum version if the original bundle was pruned.
