Add support for Plume Mainnet (v2)

[eyqs]

I manually deployed Multicall3.sol on a new deployment of Plume mainnet, but the gas usage is 1.2m because of how Arbitrum Orbit chains calculate L1 fees: https://phoenix-explorer.plumenetwork.xyz/tx/0x9a7a728978417e5f0967148d0197d4dd1632a80bed7641e6b8083d03eb7a5730

Would you be able to send me a new pre-signed transaction with e.g. gasLimit = 5_000_000 that I can use to deploy multicall3? I'm purposefully keeping the RPC URL secret so the attacker doesn't have a chance to steal the $1 in gas I'll send to the account before deploying the contract.
