Subject: [PATCH] client-cmds/nlean: use fork digest in gossip topic (leanSpec
 #622)

Change nlean's default --network value from "devnet0" to "12345678"
to match the fork digest gossipsub topic format defined in leanSpec
PR #622. All lean clients are adopting this change.

The --network flag is passed to nlean's GossipTopicProvider which
builds topics like /leanconsensus/{fork_digest}/block/ssz_snappy.
