[1.9.x] Fixed #26832 -- Added translated language name on the get_language_info documentation

The ``get_language_info()`` function provides detailed information about

languages::

    >>> from django.utils.translation import get_language_info

    >>> from django.utils.translation import activate, get_language_info

    >>> activate('fr')

    >>> li = get_language_info('de')

    >>> print(li['name'], li['name_local'], li['bidi'])

    German Deutsch False

    >>> print(li['name'], li['name_local'], li['name_translated'], li['bidi'])

    German Deutsch Allemand False

The ``name`` and ``name_local`` attributes of the dictionary contain the name of

the language in English and in the language itself, respectively.  The ``bidi``

The ``name``, ``name_local``, and ``name_translated`` attributes of the

dictionary contain the name of the language in English, in the language

itself, and in your current active language respectively.  The ``bidi``

attribute is True only for bi-directional languages.

The source of the language information is the ``django.conf.locale`` module.

Similar access to this information is available for template code. See below.
