DOC: Series.interpolate and DataFrame.Interpolate refer to methods that are no longer there.

Pandas version checks

• I have checked that the issue still exists on the latest versions of the docs on main here

Location of the documentation

https://pandas.pydata.org/docs/reference/api/pandas.Series.interpolate.html

Documentation problem

There is documentation under the limit_direction argument that refers to 'backfill' 'pad' 'bfill' and 'ffill' methods, but those are not on the list of supported methods.

Also there is no mention of how someone would do something like bfill or ffill if they look up the interpolate doc instead.

Suggested fix for documentation

Get rid of all parts that reference bfill ffill pad backfill as allowable methods.

Consider adding bfill and ffill to the "See also" section if people have come to interpolate still looking for that.
