feat: show contract-node's node logs for debugging purposes

[brunopgalvao]

It is often the case that when I am debugging ink! smart contracts, I use ink::env::debug_println! which shows up in the contract-node's node logs. Currently Pop CLI does not offer a way to see my node logs which is a deal-breaker for ink! smart contract development.

Ask: Need a way to access to contract-node’s node logs for debugging.

Also, please make sure that when contract node is spun up with the debug flags:
e.g. substrate-contracts-node -lerror,runtime::contracts=debug

Looking at node logs is also useful for debugging certain types of errors.
