Expected behaviour
TB4lite to start docked in an unobstructed area of maze world

Actual behaviour
TB4lite is half embedded into maze obstacle

To Reproduce

1. ros2 launch turtlebot4_ignition_bringup ignition.launch.py model:=lite world:=maze

[slowrunner]

Work around for time being is to click on the obstacle and select remove. Then undock action will succeed.

Or work around that preserves the maze:

1. Shift Drag Mouse Down to be looking down on world
2. Cntrl scroll Mouse Down to zoom out a little
3. Click "Translate Mode" Button (4 dir arrow cross)
4. Click on TB4lite to see three colored axis line "handles"
5. Click-Drag on green "y axis" handle or red "x axis" handle to move TB4 to an open grid crossing
6. Click on dock to show x,y,z axis handles
7. Click-Drag on green "y axis" handle or red "x axis" handle to move dock close to the TB4 again
8. Click Select Mode: Use "Rotate View" (shift drag) and "Zoom View" (cntrl drag) to view dock and TB4lite from side
9. Click Translate Mode: Adjust dock to be under TB4lite
10. Hamburger Menu: "Save World", Browse to desired folder, enter: mymaze.sdf and click OK
11. Close Gazebo, ctrl-c in shell to stop nodes
12. chmod 666 mymaze.sdf
13. sudo cp mymaze.sdf /opt/ros/galactic/share/turtlebot4_ignition_bringup/worlds/
14. Start sim with new model: ros2 launch turtlebot4_ignition_bringup ignition.launch.py model:=lite world:=mymaze
15. Shift Mouse Drag Down to be looking down on world, zoom out to view world
16. Hamburger: Save Client Configuration
17. Click "Play Button" to start sim
18. In another shell Check /dock status (ros2 topic echo /dock): "is_docked: true"
