test: update switch network test to streamline Arbitrum network addition

This commit refines the switch network test by removing redundant checks for the Localhost 8545 network and consolidating the Arbitrum network addition into a single step. This enhances test clarity and efficiency while ensuring the local node balance is verified after the network switch.
