[Question] MUJOCO environment info ERROR in the gym documentation website

[ZhaoRunyi]

Hi, I found several environment errors on the gym official website, take hale_cheetah https://www.gymlibrary.dev/environments/mujoco/half_cheetah/ as an example：

The correspondence between entries in the table is totally wrong. For instance, the Num=4 line claims that the corresponding observation means Observation=velocity of the tip along the x-axis, while its corresponding Name(in corresponding XML file)=bfoot other than rootx, and the Unit=angle(rad) other than velocity(m/s)

I found such error also appears in the new gymnasium website https://gymnasium.farama.org/environments/mujoco/half_cheetah/, and I want to know whats the real meaning of Num=(env.data.qpos.size)-1 in all kinds of MUJOCO environment. I'd really appreciate it if you fix this and answer my question fast.

This is fixed in the updated version of the website - https://gymnasium.farama.org/main/environments/mujoco/half_cheetah/
