Fix doc headers in the Hopsworks API documentation (#444)

* Fix doc headers in the Hopsworks API documentation

The headers in the main documentation are different than the headers in the Hopsworks API documentation.
In particular:
- Setup and Installation and Administration have been merged into: Setup and Administration
- Python API has been renamed to Hopsworks API
