Simulation resources are not available for the Nav2 Demo

RMW Implementation

FastRTPS

Steps to reproduce issue

Run the nav2 demo, the robot model does not appear in the rviz widget because the meshes are not available in the container. This I believe is an old issue unrelated to the recent change, just noticed it while testing.

Expected behavior

Would like to see the rover for visualization purposes.

Actual behavior

We only get tf and a geometry error saying the mesh files cannot be found.

Backtrace or Console output

I didn't realise there is a nav2 demo. I am expecting the same case for moveit2 too.

Do you think these demos can be adapter after space-ros/demos#31

Not gonna worry about this now, since we'll have time to rework that demo before the next release.
