Add update_pin_code service for Nintendo parental controls

[pantherale0]

Proposed change

Introduced a new service to update the PIN code for Nintendo devices. The service requires a device ID and a new PIN, with validation for the PIN range. Updated the corresponding YAML and strings files to include this new service and its description. Enhanced tests to cover the new functionality and ensure proper error handling for invalid devices.
