Docs: from zope.app.content import queryContentType

https://github.com/plone/plone.app.dexterity/blob/master/docs/reference/manipulating-content-objects.rst#obtaining-an-objects-schema-interface

This doesn't work:

>>> from zope.app.content import queryContentType
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'zope.app.content'

I'm not sure what's broken (the docs? zope.app.content?)

Plone 5.2.4 (5212)
CMF 2.5.0
Zope 4.5.5
