No data under dock_status and ir_opcode topics using namespace

[Gior26]

Describe the bug
When using a namespace both the /dock_status topic and the /ir_opcode topic won't produce any data.
Running the same simulation without the namespace parameter correctly returns the expected data.

To Reproduce
Steps to reproduce the behavior:

1. ros2 launch irobot_create_gazebo_bringup create3_gazebo.launch.py namespace:=robot1
2. ros2 topic echo /robot1/dock_status
3. ros2 topic echo /robot1/ir_opcode
4. No data is returned

Expected behavior
Running ros2 topic echo /robot1/dock_status and /robot1/ir_opcode should return data.

Additional context
Repository branch: Humble
ROS Version: Humble
OS: Ubuntu 22.04.3 LTS
Gazebo: Classic

Other topic such as /ir_intensity work as expected with namespaces.
