QA: enable rpc-tests (integration) using go

[lupin012]

This PR enables the new Go implementation within the integration(gnosis, ethereum, latest, remote) workflow, providing several advantages over the legacy Python scripts:

• Language-Level Benefits: Strong typing, compile-time checks, and superior concurrency via goroutines.
• Generic Interface: Features a more abstract and reusable interface compared to the previous version.
• Extensibility: Modular design suitable for diverse testing scenarios.
• Unit Testing: Includes a dedicated test suite for the tool itself.

Note on Migration:
Initially, both Python and Go implementations will be available, but only the Go version will receive future updates. The Python implementation will be deprecated and removed in future PRs.
