As the Goerli testnet will become deprecated with end of year 2023 and we've
already migrated to Sepolia testnet where we could, we'll no longer need the
Goerli-related code past that date.

As Wormhole does not support Sepolia-base L2 chains yet, we decided to still use
Goerli for the cross-chainprojects (it's still live, despite EOL planned for
2023 EOY). So we're restoring the Goerli config in those projecst and we will
remove it once Wormhole supports Sepolia L2s (or Goerli becomes unusable).
