2D Dummy Car not appearing in RViz visualization

Description

When using the 2D Dummy Car tool in AWSIM, the vehicle does not appear in RViz, while the 2D Dummy Pedestrian placed on the exact same topic is visible and works correctly.

I have confirmed that the tools and ROS topics are publishing and subscribing correctly, but the visualization fails.

Steps to Reproduce

1. Use the 2D Dummy Car tool to place a vehicle in the simulation
2. Verify that the ROS topics are publishing correctly
3. Verify that RViz is subscribing to the correct topics
4. Observe that the car does not render in RViz

Expected Behavior

The 2D Dummy Car should appear in RViz visualization, similar to how the 2D Dummy Pedestrian appears.

Actual Behavior

• The 2D Dummy Pedestrian is visible and works correctly
• The 2D Dummy Car does not appear in RViz
• Tools and ROS topics are confirmed to be publishing and subscribing correctly
• The visualization fails at the final rendering stage for the car object

Attempted Solutions

I was told to use the NPC Spawner from the [AWSIMRvizPlugins documentation](https://tier4.github.io/AWSIM/GettingStarted/Advanced/AwsimRvizPlugins/), but the visualization still fails as I could not set the NPC type:

The /awsim/awsim_rviz_plugins/npc_spawner/npc_name_list topic is not publishing anything, preventing the NPC Spawner from working.

AWSIM does not support 2D Dummies.
Instead, please use the AWSIM RViz Plugins.

I did try this out but was unable to set the NPC type as mentioned in the last part of the issue
