[Noetic] Car Junction exercise missing libcarplugin

[pawanw17]

To Reproduce:

Launch the car junction exercise on the latest RADI [3.4.2]

Instead of solving this issue for ROS1 Noetic, I think it would be more useful to solve it for ROS2 Humble and reuse the Ackermann car model that we have just developed for FollowLine exercise (in ROS2). It would be great to share the same car base (and plugin) but use different textures and plugins to adapt that model to different settings. For instance a 360 LIDAR sensor for AutoParking exercise, 3 cameras for Car Junction exercise, a single front laser for Local Navigation exercise....

The migration to ROS2 has just started (so far only FollowLine exercise and BasicVacuumCleaner exercise has been migrated, both with REACT for frontend) but it is the long term underlying infrastructure.

Understood @jmplaza I'll look into it.
