config: set the L2 gaslimit to 30 million in config

Ensures that things are smooth once https://github.com/ethereum-optimism/optimism/pull/5112
is merged. A too small of gas limit will break things after
that PR is merged. We will run with 30 million limit on mainnet,
so we should ensure that our devnet config reflects that.
