self.prefix_launch_arg not defined in the source build launch/generator.py but present in the pre-built package

Please provide the following information:

OS: Ubuntu 22.04)
ROS 2 Distro: Humble
Built from source or installed: Source
Package version: I cloned the source repo 2 days back only (if from repository, give version from sudo dpkg -s ros-$ROS_VERSION-clearpath-simulator, if from source, give commit hash)

Expected behaviour Simulation should work.

Actual behaviour Robot doesn't spawn in simulation.

To Reproduce Provide the steps to reproduce:

Follow instructions from https://docs.clearpathrobotics.com/docs/ros/tutorials/simulator/overview to run the simulator by building from source.
ros2 launch clearpath_gz simulation.launch.py
Gazebo opens but robot is not present because the platform launch file is not generated

I think it happens because self.prefix_launch_arg is not defined in the source but is present in the pre-built package. My other laptop uses the apt install, and I learned the difference that way.

This is how it appears in the deb packages

# Prefix launch arg
        self.prefix_launch_arg = LaunchFile.LaunchArg(
            'prefix',
            default_value='/world/warehouse/model/robot/link/base_link/sensor/',
            description='Ignition sensor topic prefix'
        )
        prefix_variable = LaunchFile.Variable('prefix')

self.platform_components dictionary is also different for A200
Platform.A200: [
                self.cmd_vel_node,
                self.odom_base_node,
                self.prefix_launch_arg,
            ],

This is how it is present in the source build. There is no definition for self.prefix_launch_arg and its also missing in the keys

Platform.A200: [
                self.cmd_vel_node,
                self.odom_base_node,
            ],

Other notes FYI, There might be other differences that I didn't check. Robot spawns after adding these lines to the source build.
