deploy scripts do not exist

[maikelmclauflin]

based on https://github.com/ChainSafe/ChainBridge#chain-implementations, there should be a make setup-contracts method somewhere. it seems that this does not exist on the current main branch. is it on a different branch perhaps?

@maikelmclauflin It's now make rebuild-contracts on the ChainBridge repo. We should update those docs 🙏
