Fix mypy false positives regarding to_pydantic

[thejaminator]

Description

Closes #2015

Fixes false positives with the mypy plugin. Happened when to_pydantic was called on a type that was converted pydantic with all_fields=True.

Also fixes the type signature when to_pydantic is defined by the user.

from pydantic import BaseModel
from typing import Optional
import strawberry


class MyModel(BaseModel):
    email: str
    password: Optional[str]


@strawberry.experimental.pydantic.input(model=MyModel, all_fields=True)
class MyModelStrawberry:
    ...

MyModelStrawberry(email="").to_pydantic()
# previously would complain wrongly about missing email and password
