### Pandas version checks - [X] I have checked that the issue still exists on the latest versions of the docs on `main` [here](https://pandas.pydata.org/docs/dev/) ### Location of the documentation https://pandas.pydata.org/docs/dev/reference/api/pandas.Grouper.html#pandas.Grouper ### Documentation problem *args and **kwargs is not required anymore ### Suggested fix for documentation *args and **kwargs should be removed
