feat: implement builder pattern for JsonrpcErrorError

[hashemix]

📌 Summary

To improve usability and maintainability, we've introduced a new approach for creating JsonrpcErrorError objects using a builder pattern. This makes the API more ergonomic and allows method chaining.

✨ Changes Made

• Enhanced schema_utils by adding a builder pattern to JsonrpcErrorError.
• Deprecated the get_method() functions in favor of method() to improve consistency.

💡 Additional Notes

The new functionalities make creating a JsonrpcErrorError object much easier.

Old Approach

JsonrpcErrorError::new(
            schema_utils::RpcErrorCodes::method_not_found,
            "Method not found!".to_string(),
            None,
        );

New Approach

JsonrpcErrorError::method_not_found()

• overriding the message and passing data:

JsonrpcErrorError::method_not_found()
        .with_message("Method is not supported!".to_string())
        .with_data(Some(json!({"details": "No implementation found for this method."})))
