Describe the bug

If you create your TypeVars in a private module, then re-export them via a public module, they lose their type comments when documented via an automodule directive.

In the reproducer below, V appears in the output, while T does not.

I will submit a PR fixing this with the reproducer as a unit test.

How to Reproduce

mymodule/_private.py:

from typing import TypeVar

T = TypeVar("T", bound=int | str)
"""A reimported TypeVar"""

mymodule/__init__.py:

from ._private import T

from typing import TypeVar

V = TypeVar("V")
"""A locally defined TypeVar"""

__all__ = ["T", "V"]

index.rst:

.. automodule:: mymodule
