Remove the hard-coded peer id from the debug message in p2p_v2_misbehaving.py.
asyncio’s non-deterministic task scheduling might cause peer2’s connection to happen before peer1’s. since we test that peer2 remains connected, any disconnection must originate from peer1, making the specific peer id not necessary for test correctness. so we can remove the hard coded peer id from the expected debug log message.
Fixes #34035.
