This change creates a bidirectional bridge, but that is not necessary. The original version should work as is and bridges data from Gazebo -> ROS. Looking at #3761 (comment), I think the best otion is to wrap the whole thing in single quotes

Suggested change
$ ros2 run ros_gz_bridge parameter_bridge /lidar2@sensor_msgs/msg/LaserScan@ignition.msgs.LaserScan --ros-args -r /lidar2:=/laser_scan
$ ros2 run ros_gz_bridge parameter_bridge `/lidar2@sensor_msgs/msg/LaserScan[ignition.msgs.LaserScan` --ros-args -r /lidar2:=/laser_scan


To visualize the data from the lidar in ROS 2 you can use Rviz2:
