Use offline mode for Anvil ZK

[ilanolkies]

The mainnet fork was default and it is not working out of the box. I moved to --offline that doesn't fork, and that also is of my preference.

Why

The changes ensure that the Anvil zkSync Docker container runs in offline mode by adding an --offline flag to its execution command. This is crucial for scenarios where network isolation is required or in testing environments where external network access should be limited to simulate or enforce certain conditions.

What

• framework/components/blockchain/anvil_zksync.go
  • Added the --offline flag to the Anvil zkSync container's entrypoint command. This modification allows the container to operate without needing external network access, providing a more controlled environment for testing or specific operational requirements.
