Examples not loading on Garden and Harmonic

[Luczia]

Hi,

I can't get any gz_ros2_control_demo example to work either on Rolling + Harmonic or Rolling + Garden

Configuration :
Docker Ubuntu 22.04 on Ubuntu 22.04
ROS Rolling + Garden or ROS Rolling + Harmonic
ros_gz (ros2), gz_ros2_control(main) built from source

Step to reproduce :
Command "ros2 launch gz_ros2_control_demos diff_drive_example.launch.py" (or any other example from the doc)

Error :

No error (red message) displayed in the terminal, but the world in Gazebo Sim is empty.

I can reproduce this issue but get this error here:

[create-4] [ERROR] [1710974612.168064338] [ros_gz_sim]: Must specify either -file, -param, -stdin or -topic
[ERROR] [create-4]: process has died [pid 85887, exit code 255, cmd '/opt/ros/rolling/lib/ros_gz_sim/create --ros-args --params-file /tmp/launch_params_rck07jjx'].

I think that the changes introduced with #211 don't work with binary installation of ros_gz_sim because there was no release of ros_gz_sim since gazebosim/ros_gz#475. @ahcorde

Using gz_ros2_control 1.2.0 still works.

Should be fixed with the release 1.0.0 of ros_gz_sim
