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)

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.
