contracts-governance: mint manager deploy

Add a deploy script for the new mint manager. To review this,
check the `cast` calls in the mint manager implementation
deploy script. The owners of the `MintManager` are preserved,
double check that in the `deploy-config` directory against
what the cast calls return.

To deploy this, the new implementation needs to be deployed
and then the existing owner of the `MintManager` needs to
send a transaction to the `MintManager` calling `upgrade(address)`
to the new implementation of the `MintManager`.
