The `hardhat.json` deploy config is used for the internal
solidity tests. It is used because the default chain id
is the same as what hardhat uses for testing and the chain
id is what is used to specify which deploy config to use.

The values are updated to ensure that sane, testable values
are configured into the in memory tests for https://github.com/ethereum-optimism/optimism/pull/7928.
