chore: deploy network without contracts (#19064)

This PR fixes the deployment scripts where they would try to deploy a
new set of rollup contracts instead of using the names in
https://github.com/AztecProtocol/networks

This PR also adds snasphost to devnet-next so that new nodes can more
easily be spun up.
