// DeployWithDeterministicDeployer deploys a smart contract on a simulated Ethereum blockchain using a deterministic deployment proxy (Arachnid's).
//
// Parameters:
// - backend: A pointer to backends.SimulatedBackend, representing the simulated Ethereum blockchain.
// Expected to have Arachnid's proxy deployer predeploys at 0x4e59b44847b379578588920cA78FbF26c0B4956C, NewL2BackendWithChainIDAndPredeploys handles this for you.
// - contractName: A string representing the name of the contract to be deployed.
//
// Returns:
// - []byte: The deployed bytecode of the contract.
// - error: An error object indicating any issues encountered during the deployment process.
//
// The function logs a fatal error and exits if there are any issues with transaction mining, if the deployment fails,
// or if the deployed bytecode is not found at the computed address.
