Improve air-gapped support #310
Description
Using Image Factory in air-gapped environments is difficult, as downloading Talos Linux versions, schematics, and models requires internet access. Existing instructions are not clear enough about preparing artifacts ahead of time and transferring them into a disconnected environment.
Provide official instructions on how to:
- Download and package Talos Linux versions, schematics ahead of time.
- Transfer these artifacts into an air-gapped environment.
- Use them with Image Factory without requiring internet connectivity.
