example templates: describe why the volume mounts (/dev, /lib/firmware) are required

[Rui Lopes]

The examples (e.g. ubuntu or windows) should describe why they use the following volume mounts:

    volumes:
      - /dev:/dev
      - /dev/console:/dev/console
      - /lib/firmware:/lib/firmware:ro

Maybe at https://docs.tinkerbell.org/deploying-operating-systems/the-deployment/

Thanks for the feedback @rgl - if you are up for attempting to document this, please let me know. I'd be happy to review a PR that does this.

@thebsdbox - do you have any insight into who/what uses these volume mounts?

[Rui Lopes]

@tstromberg, I'm only sure about /dev, which is needed when the action needs to write to a physical device like a disk.
