Fixed #23355 -- Updated admin jQuery to 1.11.1.

Django admin Javascript makes use of the `jQuery`_ library.

To avoid conflicts with user-supplied scripts or libraries, Django's jQuery

(version 1.9.1) is namespaced as ``django.jQuery``. If you want to use jQuery

(version 1.11.1) is namespaced as ``django.jQuery``. If you want to use jQuery

in your own admin JavaScript without including a second copy, you can use the

``django.jQuery`` object on changelist and add/edit views.

.. versionchanged:: 1.8

    The embedded jQuery has been upgraded from 1.9.1 to 1.11.1.

The :class:`ModelAdmin` class requires jQuery by default, so there is no need

to add jQuery to your ``ModelAdmin``’s list of media resources unless you have

a specific need. For example, if you require the jQuery library to be in the

  <django.contrib.admin.ModelAdmin.delete_view>` displays a summary of objects

  to be deleted on the deletion confirmation page.

* The jQuery library embedded in the admin has been upgraded to version 1.11.1.
