Expected behaviour

When using discovery server, create3 topics are published and available. e.g.,
ros2 topic echo /battery_state
ros2 topic echo /wheel_vels
ros2 topic echo /wheel_status

Actual behaviour

1. Create3 topics are not available via ros2 topic echo
2. ros2 topic info shows no publisher for create3 topic
3. no create3 republisher node is found in ros2 node list
4. undock button does not work

See #462 for screenshots of behavior

I was able to make the discovery server configuration work by giving the robot a namespace through the turtlebot4-setup command. May be related to #425 (comment), but I'm unsure if the issue is the same, or if they are just similar issues. Unfortunately, I don't have time to look into it more. For the time being, I will be using namespaces.

@mbergman257 Currently there is a bug with Discovery Server that requires a namespace to be present. The fix has already been merged in but is pending iRobot's next release of the create3_republisher.
