Need to add colcon.pkg file to all pure cmake packages.

[Levi-Armstrong]

For colcon to find cmake package in underlays and plugins this file needs to be added to each cmake package. Update the contents below with the package name and since we are using ros_industrial_cmake_boilerplate it will handle the rest.

file name: colcon.pkg

{
    "hooks": ["share/<package_name>/hook/ament_prefix_path.dsv", "share/<package_name>/hook/ros_package_path.dsv"]
}
