Correct a typo of version number for interpolate()
Correct a typo of version number in the docstring of _shared_docs['interpolat e'] which is the docstring for pandas.core.resample.Resampler.interpolate, pandas.DataFrame.interpolate, panda s.Series.interpolate, and pandas.Panel.interpolate, and in documentation/user_guide/missing_data about the limit_area keyword argument in interpolate(). The reference can be found at https://github.com/pandas-dev/pandas/issue s/8000#issuecomment-465802842.
