oc mirror delete command is incorrect.

Current:
~~~
$ oc mirror delete --v2 --delete-yaml-file <previously_mirrored_work_folder>/delete/delete-images.yaml docker:/ <remote_registry>
~~~

Expected:
~~~
$ oc mirror delete --v2 --delete-yaml-file <previously_mirrored_work_folder>/working-dir/delete/delete-images.yaml docker://<remote_registry>
~~~
