Documentation and code are inconsistent

Hi!

Thanks for your team's great work!

I read your docs carefully and see for tasks like, "StackCube-v1", "PickSingleYCB-v1", etc., do support xarm. However, when I run the code like env = gym.make( "PickSingleYCB-v1", obs_mode="state", robot_uids="xarm", num_envs=16 ) it still keeps saying the robot is not supported. So, how can I use xarm for these tasks? Thanks in advance.
