Refrain from starting anvil-zksync instance after replay-tx

[dutterbutter]

Description

Currently when users make use of replaying a transaction, an instance of anvil-zksync is started there after.

Solution

Do not start an instance of anvil-zksync after replaying the transaction. Making it easier to review the details of the replayed transaction.

This would basically mean having node setup, executor spawned, and applying the replay transactions within:

Command::ReplayTx(replay_tx) => { ... }

And then exit. May need to think about refactoring main.rs before otherwise it would be a lot of redundant code between Command::ReplayTx and Command::Fork | Run.
