There is a problem with the json, when it is trying to marshal "null" into a string value...

After changing CPUType to map[Arch]*string, it is a problem to express as jsonschema.

Also, it means that we don't have to carry the list of architectures in the "empty" yaml?

Made some similar changes to ssh.localPort and Rosetta omitempty, but will post separately

Also the (text of the) lines are not removed, they are just translated into comments instead.

When uncommented, the default is reconstructed (could use "" or null for empty values)
