Updates required for lab1

[aburdenthehand]

It looks like our KubeVirt labs are out of date :( It would be great if someone could run through the labs and update the guide accordingly. This is an opportunity to also increase the amount of information if need be.

Now that we're on a slower release cadence, we should be able to update these labs on an annual basis, tied to the most recently released version, which will be supported for ~12 months. Running and updating the labs could be a useful exercise for new contributors, provided they are supported if and when they need to troubleshoot changes in the procedure.
