Nested classes being flagged as wrong as of 0.4.12

[eliasmistler]

Describe the bug
Nested class definitions are being marked as of the latest version.
I'm pretty sure it wasn't a problem in 0.4.11, but I can't downgrade now as I've updated my PyCharm and 0.4.11 is not compatible with PyCharm 2024.1.

To Reproduce
You can use the following example code:

from pydantic import BaseModel


class Outer(BaseModel):
    class Inner(BaseModel):
        inner_attr: str

    inner: Inner
    outer_attr: str


outer = Outer(inner=Outer.Inner(inner_attr='foo'), outer_attr='bar')

The call to Outer.Inner will be highlighted as a warning

Expected behavior
This should not be highlighted as an issue
