Remove support for Goerli testnet (#755)

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.

[UPDATE post-2023]: As Wormhole does not support Sepolia-base L2 chains
yet, we decided to still use Goerli for the cross-chainp rojects (Goerli
it's still live, despite EOL planned for 2023 EOY). So we're not
removing Goerli config from the cross-chain projects - we will handle
that in a later date (once Wormhole supports Sepolia L2s or Goerli
becomes unusable).
