Unable to parse valid port from substrate-contracts-node v0.42.0

[cmichi]

The log output changed with paritytech/polkadot-sdk@09254eb. Our parsing can't handle that currently.

The error appears when runing the E2E tests on a contract:

$ cargo test  --features e2e-tests   
…
thread 'static_buffer::e2e_tests::e2e_run_out_of_buffer_memory' panicked at /Users/michi/projects/ink/crates/e2e/src/node_proc.rs:221:17:
valid port expected for tracing line, got '64224,[::1]:64225'

---- static_buffer::e2e_tests::buffer stdout ----

The issue wasn't catched in our CI. The reason is that we (accidentally) don't pull the most recent substrate-contracts-node binary release for all CI stages. In that case the substrate-contracts-node binary present in the Docker image was used, and that one is old.
