DOC: fix PR02 errors in docstring for pandas.Series.rename_axis (pandas-dev#57239)

* DOC: fix PR02 errors in docstring for pandas.Series.rename_axis

* Refactor Series.rename_axis and NDFrame.rename_axis to have separate docstrings

* removed unnecessary columns ref in docstring for Series

* removed another unnecessary columns ref in docstring for Series
