Broken paths for ped scenarios

[Steplerchik]

Dear developers,

I'm trying to run the simulation by the example provided in your documentation. I've built the system from the master branch.

However, I'm facing several problems. The first one is about broken paths:

arena_rosnav_sim | [ INFO] [1689075067.757226281]: Loading scene [/home/docker_arena/catkin_ws/src/utils/arena-simulation-setup/world/map_empty/scenarios/map_empty.xml] for simulation
arena_rosnav_sim | [ INFO] [1689075067.757348850]: Could not load the given scene file, trying to load empty scene

The second one is the problem, described in this issue. PLease, could you help to solve all the problems? Thank you in advance!

The broken paths is a simple fix. The world directory is actually called worlds and the scenario directory is actually called ped_scenarios.

In release 0.2.2, edit the start_arena.launch file line 146 to <param name="scene_file" value="$(find arena-simulation-setup)/worlds/$(arg world_file)/ped_scenarios/$(arg world_file).xml" type="string"/>

The other problem doesn't have a solution yet, but is new to commit 91cee6f. Switching to 0.2.2 avoids it for now.
