Generate a network with a random ID is incorrect

[blitztide]

The API spec leads you to believe that the route for a random network ID is:
/controller/network/{controllerID}

But it requires six underscore characters to generate the ID, or it will return a 404 error
/controller/network/{controllerID}______

It is shown in the docs https://docs.zerotier.com/controller/ as requiring the underscores, but not in the OpenAPI spec or API docs.
