Suggested title: Installing a SNO cluster with OCP version before 4.16 with infrastructure operator

Content:

If you're installing a SNO cluster with an OCP version before 4.16, ensure your InfraEnv CR and your booted host are using the same OCP version you're installing the cluster with.

Before booting any hosts with the discovery ISO, either create or edit your InfraEnv to include the following:

apiVersion: agent-install.openshift.io/v1beta1
kind: InfraEnv
spec:
  osImageVersion: 4.15 <1> 

<1> This version should match the cluster version you intend to install

The SNO cluster should complete installation successfully.
