E.g., launch test

Hi, I’m interested in working on this issue.
Before starting, could you confirm whether this system-test requirement is still relevant with the current micro-ROS diagnostics stack? If so, I’d be happy to add a launch/integration test covering the updater + bridge path into ROS 2 diagnostics.
