**Describe the bug** When writing generators, the yield type includes the `Iterator` type. **To Reproduce** Example file: ```py from typing import Iterator def a_generator() -> Iterator[int]: """Generate a number. Yields: A number. """ yield 1 ``` **Expected behavior** The yield type should be the *inner* type, for example for `Iterator[int]` it should be `int`. **Screenshots** In this case the `yield`ed type is actually `int`, not `Iterator[int]`.  **System (please complete the following information):** - `mkdocstrings-python` version: 1.1.2 - Python version: e.g. 3.11 - OS: Linux (Debian testing)
