bug: PEP695 `type MyAlias = int` not included in docs while `MyAlias: TypeAlias = int` works fine

[mzebrak]

Description of the bug

When the PEP695 syntax is used for type alias declaration, no docstring is gathered.

it should be treated the same way as:

from typing import TypeAlias

SomeType: TypeAlias = int
"""Type alias docstring"""

To Reproduce

type SomeType = int
"""Type alias docstring"""

Expected behavior

Should gather type alias and show it on the mkdocs site like when TypeAlias is used:
