Description of problem:
mirrored images have a mismatch on sha in air gapped ocp cluster deployment

As per cm#42 from this BZ(
https://bugzilla.redhat.com/show_bug.cgi?id=1800674), customer applied the workaround and the issue ws resolved but later the same issue came back in ocp.4.5. 


from cm#42, workaround was: To use " --filter-by-os='.*' instead of "`--filter-by-os='linux/amd64`" 

Now customer is having the same issue in ocp4.6.x and the customer wanted to appy the same workaround to use " --filter-by-os='.*'" but this option is not even available in ocp.4.6x.

- from customer:
$ /var/lib/import/bin/oc adm catalog mirror registry.redhat.io/redhat/redhat-operator-index:v4.5 localhost:7000/redhat-operator -a /var/lib/import/plays/auth.json --filter-by-os='.*' --max-components=3 --to-manifests=/var/lib/import/olm/redhat-operator --path=/:/var/lib/import/olm/redhat-operator/image --insecure 
                                                                                                                                     
error: the image is a manifest list and contains multiple images - use --filter-by-os to select from:

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