Description of problem:
The syntax for the command in removing the configuration from the Cluster Network Operator (CNO) configuration object is incorrect.
oc patch Network.operator.openshift.io cluster --type='merge' \ --patch '{"spec":{"migration":null}}'

Command is under step 1 procedure in the following link:
https://docs.openshift.com/container-platform/4.16/networking/ovn_kubernetes_network_provider/migrate-from-openshift-sdn.html#removing-nncp-limited-live-migration.adoc_migrate-from-openshift-sdn

How reproducible: Consistently

Steps to Reproduce:
1. Run the command as documented will fail
2. The following error will occur:
$ oc patch Network.operator.openshift.io cluster --type='merge' \ --patch '{"spec":{"migration":null}}'
error: must specify --patch or --patch-file containing the contents of the patch

Actual results:
Error
Expected results:
Patch is successfully applied

Additional info:
The command should be two lines like the other examples in the doc. The --patch should be on the next line after the backslash.
