Description of problem:

In the "Mirroring images to a private registry for a disconnected installation" module, when creating the image set configuration in imageset-config.yaml, n-1 images are not included in the image set configuration (imageset-config.yaml).

Prerequisites (if any, like setup, operators/versions):

• A running OpenShift Container Platform cluster, version 4.10 or greater.
• A host with access to the Internet to obtain the images to populate the mirror repository.
• Installation of the OpenShift CLI (`oc`).
• Access to the cluster as a user with the `cluster-admin` role.

Steps to Reproduce

1. Create a mirror registry on a host with Internet access.
2. Install the `oc-mirror` OpenShift CLI plug-in to mirror registry images.
3. Configure registry authentication.
4. Create the image set configuration and save it to a file called `imageset-config.yaml`.

Actual results:

All notebook images are not mirrored due to only one version of each notebook image being included in the YML file (imageset-config.yaml).

Expected results:

Both n and n-1 images should be included in the image set configuration (imageset-config.yaml).

Reproducibility (Always/Intermittent/Only Once):
