How can i build a air gapped vm image so that rke2 can bootstrap automatically?

@HenryGuo1019 you can take inspiration from here for image building in Air Gapped mode.
The example shown there is based on Docker, but the same principles apply.

The idea is:

• Use a base OS that supports cloud-init or ignition.
• Put prerequired files for your RKE2 version in a specific target folder ( /opt/rke2-artifacts ) (TAR files that you can download from the RKE2 release page)
• Specify true in RKE2ConfigTemplate.spec.agentConfig.airGapped.
