fix!: remove node level pubsub topic concept

For an edge node, there is no such thing as a "pubsub topic configuration". An edge node should be able to operate for any possible shard, and it is a per-protocol matter (eg send message with light push).

A relay node do subscribe to shards, but in this case, even metadata protocol does not need to advertise them, this is already handled by gossipsub.

Only service node should advertise their shards via metadata protocol, which is out of scope for js-waku.
