Industrial CI CMake tests error

Attaching the repository to workspace https://github.com/husarion/rosbot_ros/tree/ros2-combined-microros with industrial CI doesn't pass tests:

$ ( source /opt/ros/humble/setup.bash && cd /root/target_ws && colcon test-result --verbose; )

Start by reproducing the reported command in the ros2-combined-microros workspace, focusing on /root/target_ws/src/rosbot_ros/src/micro_ros_msgs and its ament copyright test. Check why CONTRIBUTING.md is expected but missing, then rerun colcon test-result --verbose; done means the micro_ros_msgs copyright test reports no failures.
