bpo-30354: Update data model documentation for super() (GH-1561)
The data model section of the language reference was written well
before the zero-argument form of super() was added.
To avoid giving the impression that they're doing something
unusual, this updates the description of `__new__` and `__init__`
to use the zero-argument form.
Patch by Cheryl Sabella.
