Bug Report

stubgen does not properly generate ellipses for default values set in the scope of the class body of a Pydantic model.

To Reproduce

Running stubgen -m example

# example.py
from pydantic import BaseModel


class Foo(BaseModel):
    abc: int = 1
    xyz: str = "abc"

Should produce

Expected Behavior

# example.pyi
from pydantic import BaseModel

class Foo(BaseModel):
    abc: int = ...
    xyz: str = ...

stubgen should be populating the default annotation with ellipses, instead they are missing.

Actual Behavior

# example.pyi
from pydantic import BaseModel

class Foo(BaseModel):
    abc: int
    xyz: str
