Pull request description:

  per the IRC discussion today at http://www.erisian.com.au/bitcoin-core-dev/log-2021-01-19.html#l-87

  - return a more helpful string name for `Network::NET_UNROUTABLE`: "not_publicly_routable" instead of "unroutable"
  - update the RPC getpeerinfo "network" help, and automate it and the getnetworkinfo "network#name" and the -onlynet help doc generation
