Dock not displayed in Rviz when running AWS house

[alsora]

Describe the bug
When running the AWS house the dock does not appear in RVIz, although it's in the simulated environment.
On the other hand, when running empty world, we do see the dock in RViz (even if bugged, see #75)

To Reproduce
Steps to reproduce the behavior:
Run ros2 launch irobot_create_gazebo aws_small.launch.py

As of now, the dock is present in RViz with the aws house. The issue is that it's far away from the robot

The dock is spawning at 0, 0, 0 as specified by the static_transform_publisher, https://github.com/iRobotEducation/create3_sim/blob/main/irobot_create_description/launch/include/dock.py#L79

So the question is what do we do with the robot? spawn it docked wherever the dock is?
