DOC: Clean dubious docstring
Fixes #50344

- [x] closes #50344 


Thanks @luke396 this looks nice. I think in general we don't document `__init__` but the class itself. Do you mind moving what's in the `__init__` docstring to the class docstring? I think that will be even better and more consistent. Thanks!  > Thanks @luke396 this looks nice. I think in general we don't document `__init__` but the class itself.

I change it, what about this time? 😃  > Looks great. Just added couple of small things, you can commit them from the github UI
