Configuration documentation incorrectly states that PYSPARK_PYTHON's default is "python"

The configuration documentation states that the environment variable PYSPARK_PYTHON has a default value of python:

In fact, the default is python2.7:

The change that introduced this was discussed here:

https://github.com/apache/spark/pull/2651

Would it be possible to highlight this in the documentation?
