chore: Update nwaku to point to the new RLN contract

[stubbsta]

Background

A new RLN contract has been deployed to Linea Sepolia testnet (see waku-org/pm#228 and waku-org/pm#258). This requires updates to the nwaku repo.

Details

Updates need to be made to the nwaku repo to point to the new contract and then update nwaku-compose to use this new nwaku

The old/current contract as used in nwaku repo: 0xCB33Aa5B38d79E3D9Fa8B10afF38AA201399a7e3

The New contract is deployed on Linea Sepolia:
Implementation is here: 0x5536F82a106D8C1f5F61D111DF57cae6218F6b54
Implementation is here: 0xde2260ca49300357d5af4153cda0d18f7b3ea9b3
Proxy is here: 0xB9cd878C90E49F797B4431fBF4fb333108CB90e6

The code needs to be updated with the new contract here:
nwaku repo:
https://github.com/waku-org/nwaku/blob/master/apps/sonda/docker-compose.yml#L12
https://github.com/waku-org/nwaku/blob/master/apps/sonda/register_rln.sh#L27
https://github.com/waku-org/nwaku/blob/master/waku/factory/networks_config.nim#L25

These are related issues that are out of scope of this issue and still need to be created:

• update the nwaku RLN contract registration tools
• update nwaku RLN tests for the new contract bytecode and registration tools.
• update the contract and registration in nwaku-compose.

These updates are also required in nwaku-compose:
https://github.com/waku-org/nwaku-compose/blob/master/docker-compose.yml#L6
https://github.com/waku-org/nwaku-compose/blob/master/register_rln.sh#L26
