Mypy complains wrongly about to_pydantic when using a pydantic type that was converted with all_fields=True

[thejaminator]

Describe the Bug

I introduced this bug in 0.118.0

class MyModel(BaseModel):
    item: str


@strawberry_from_pydantic(model=MyModel, all_fields=True
)
class StrawberryModel:
    ...

StrawberryModel(item).to_pydantic()
# mypy errors incorrectly

I should be able to fix it by infering that all_fields=True if there are no strawberry.auto declarations in the class
