Log implementation address of smart contracts deployed with Openzeppelin Defender.

[alysiahuggins]

When deploying with foundry and openzeppelin defender, logs are explicitly written to a file in the deployment script https://github.com/EspressoSystems/espresso-sequencer/pull/1248. At the time of writing, the proxy address is recorded but not the implementation address as retrieving it within the deployment script has not been straight forward thus far. Log the implementation address in the deployment logs.
