gnd: Replace --network with --network-file and update networks.json in add command

- Replace the --network flag with --network-file flag (default: networks.json)
  to match graph-cli's add command interface. The network is now always
  determined from the existing manifest's first data source.
- After adding a new data source, automatically update networks.json with
  the new contract's address and start block using update_networks_file().
