Missing XML File

Hey,
I was trying to implement the predictive sampling planner in the MJX module inside the python section. I tried running the existing example that was set to mjx_insert_cube.xml inside the insert.py file [https://github.com/google-deepmind/mujoco_mpc/blob/main/python/mujoco_mpc/mjx/tasks/insert.py](url) , but the xml file did not exist in the repository.
