* docs: Update Python 2 doc links

Update links from Python 2 to Python 3

Signed-off-by: Abhijeet Kasurde <akasurde@redhat.com>

* use docs.python.com/3/ everywhere, except onethat should remain 2.6

* refer to python 3 in module docs and comments

* format two python docs links as list

* updates links in unwanted.py test file

* per matt clay, this should link to python 2

 .. note:: The key part in the key=value pairs will be converted into lowercase inside the ansible_local variable. Using the example above, if the ini file contained ``XYZ=3`` in the ``[general]`` section, then you should expect to access it as: ``{{ ansible_local['preferences']['general']['xyz'] }}`` and not ``{{ ansible_local['preferences']['general']['XYZ'] }}``. This is because Ansible uses Python's `ConfigParser`_ which passes all option names through the `optionxform`_ method and this method's default implementation converts option names to lower case.
