Which section(s) is the issue in?

Installing the legacy Migration Toolkit for Containers Operator on OpenShift Container Platform 3 and other sections of the whole document. This is present in older version of OpenShift documentation too, ex. 4.10.

What needs fixing?

sudo is not required for the podman commands. We can remove the unnecessary privilege escalation allowing a broader set of users to run it.

Example of existing code:
sudo podman cp $(sudo podman create registry.redhat.io/rhmtc/openshift-migration-legacy-rhel8-operator:v1.7):/operator.yml ./

Example of the sudo removal:
podman cp $(podman create registry.redhat.io/rhmtc/openshift-migration-legacy-rhel8-operator:v1.7):/operator.yml ./
