Extra "in" in "Contributing to pandas" documentation

[mattayes]

Problem description

Section: Contributing to pandas
Subsection: About the pandas documentation
Link: http://pandas.pydata.org/pandas-docs/version/0.21.0/contributing.html#about-the-pandas-documentation

The second sentence of the last paragraph contains an extra "in" (bolded):

The utility script scripts/api_rst_coverage.py can be used to compare the list of methods documented in doc/source/api.rst (which is used to generate the API Reference page) and the actual public methods. This will identify methods documented in in doc/source/api.rst that are not actually class methods, and existing methods that are not documented in doc/source/api.rst.

Expected Output

The utility script scripts/api_rst_coverage.py can be used to compare the list of methods documented in doc/source/api.rst (which is used to generate the API Reference page) and the actual public methods. This will identify methods documented in doc/source/api.rst that are not actually class methods, and existing methods that are not documented in doc/source/api.rst.

just send a PR, no need to make an issue for docs that you find confusing.

@jreback Sounds good, will do.
