Changed this to use the semantic model, and allow raise NotImplementedError (without argument) and raise NotImplemented.

Why do you allow raise NotImplemented? NotImplemented is not an exception. It should never be raised. NotImplemented can be returned by comparison operators.

We have separate rules to guard against raise NotImplemented. But if the entire function is raise NotImplemented, it's almost certainly intended to be raise NotImplementedError, right?

What's the purpose of this example?

To verify that we treat raise NotImplemented like raise NotImplementedError. (Just to be clear, these aren't examples, they're tests.)
Summary
As discussed in #10083 (comment), stubs detection now also covers the case where the function body raises NotImplementedError and does nothing else.
Test Plan
Tests for the relevant cases were added in B006_8.py
