 * Initiates a [withdrawal](https://community.optimism.io/docs/protocol/withdrawal-flow/#withdrawal-initiating-transaction) on an L2 to the L1.
 *
 * Internally performs a contract write to the [`initiateWithdrawal` function](https://github.com/ethereum-optimism/optimism/blob/283f0aa2e3358ced30ff7cbd4028c0c0c3faa140/packages/contracts-bedrock/src/L2/L2ToL1MessagePasser.sol#L73)
