Describe the issue:
Chapter 2. Downloading log files and diagnostic information using must-gather of Troubleshooting OpenShift Data Foundation [1] has an instruction to mirror the ODF must-gather component as below.

~~~
Optional: If OpenShift Data Foundation is deployed in a disconnected environment, ensure that you mirror the individual must-gather image to the mirror registry available from the disconnected environment.

$ oc image mirror registry.redhat.io/odf4/odf-must-gather-rhel9:v4.13
~~~

There is another way to mirror the ODF must-gather component using the oc-mirror[2] plugin but it's not documented.

Describe the task you were trying to accomplish:
Document how to mirror the ODF must-gather component using the oc-mirror plugin.

Suggestions for improvement:
Would be nice to document ImageSetConfiguration example like below.
