RubiksCube222EnvLBL.reset() got an unexpected keyword argument 'scramble'

Good evening, I was checking the boilerplate code in the documentation page and I receive this error in the reset method:

`TypeError Traceback (most recent call last) Cell In[5], line 5 2 import rubiks_cube_gym
4 env = gym.make('rubiks-cube-222-lbl-v0')
----> 5 env.reset(scramble="R U R' U' R' F R2 U' R' U' R U R' F'")
7 for _ in range(4):
8 env.render()

Actual type: {type(result)}" 191 )

TypeError: RubiksCube222EnvLBL.reset() got an unexpected keyword argument 'scramble'` I am using gymnasium version 0.29.1. If I remove the 'scramble' from the code it runs fine. How could this be fixed?

Thank you very much.

Well, looking at the code I found that the example in the documentation should be fixed as the correct line of code should be: options={"scramble": "R U R' U' R' F R2 U' R' U' R U R' F'"}. With this change, this part of the code works as expected.
