Fix graphviz_draw return type annotation and docstring (PIL.Image -> PIL.Image.Image) (#1637)

* Fix graphviz_draw return type annotation and docstring

graphviz_draw was annotated and documented as returning the PIL.Image
module instead of the PIL.Image.Image class. Because graphviz.py does
`from PIL import Image`, `Image` is the module, so `-> Image | None`
annotated the return with a module rather than the image class.

Correct the runtime annotation to `Image.Image | None` and the
`:returns:`/`:rtype:` docstring to `PIL.Image.Image`. The stub
(graphviz.pyi) already imported the class and was correct, so it is
left unchanged.

Add tests/visualization/test_graphviz_typing.py with two guards:
- a runtime check (get_type_hints + docstring) for the implementation,
  which is what actually regressed here since the stub shadows the
  implementation for static type checkers; and
- a static assert_type check for every stub overload, wired into the
  `stubs` nox session via mypy.

Fixes #1357

* Remove poorly written tests and keep release notes minimal
