🤷‍♀️ not sure, could just not print that line if not using extract.

I don't think the release name is important for the output of openshift-install version
oc adm release info <release image> should be the correct way for user to find that out.

@wking wdyt? doesn't matter to me either way, I'm adding the info for oc, don't have to use it in installer. Maybe installer should print the payload version if/only if using 'oc adm release extract', leave the line out otherwise.

closing since seems this isn't required and the oc change would not be backwards compatible.
