sdk: fix deposit-eth task

The address was not being referenced resulting in a bug. We should
delete this task eventually and have coverage of this with op-e2e
although this does cover the hardhat deployments which op-e2e does
not cover. Perhaps this should live in hive then longer term.
Ported from the `feat/mainnet` branch.
