Update checking-mco-node-status.adoc

[s-dharma]

In the Red Hat official documentation, the "oc describe" command has "-o yaml" in the end. This "-o yaml" should not be there in the "oc describe" command.

Currently the command in the document is : oc describe machineconfignode/<machine_config_node_name> -o yaml

The correct Command is : oc describe machineconfignode/<machine_config_node_name>

The "oc describe" command should not have "-o yaml" in the end.

Hi @s-dharma. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
