chore: decouple listen and announced addresses

[gabrielmer]

Details

Currently our "Listening on..." log does not show the addresses we are actually listening on - it prints the addresses that we announce.
This is a bit misleading and therefore, we want to separate it into two different log prints: one that includes the addresses our node is listening on and another with the addresses the node wants to announce to the outside world.

For the listen addresses, we also want to include the node's local IP, which is currently not displayed in nwaku. The local IP is logged in go-waku and it's an address where our node is reachable. Therefore, it makes sense to also include it in nwaku, both for consistency and convenience.

Acceptance criteria

• two different logs are printed to the console, one with listen addresses and other with announced addresses
• local IP is included in the listen addresses log
