defining a validator causes mypy: maximum semantic analysis iteration count reached
### Initial Checks

- [X] I have searched GitHub for a duplicate issue and I'm sure this is something new
- [X] I have searched Google & StackOverflow for a solution and couldn't find anything
- [X] I have read and followed [the docs](https://docs.pydantic.dev) and still think this is a bug
- [X] I am confident that the issue is with pydantic (not my code, or another library in the ecosystem like [FastAPI](https://fastapi.tiangolo.com) or [mypy](https://mypy.readthedocs.io/en/stable))


### Description

Hi, I'm getting the mypy `INTERNAL ERROR: maximum semantic analysis iteration count reached` error when defining a validator in a model via a helper function. Note that declaring the type of the validator makes mypy not crash anymore (see example). Also the issue occurs only with `pydantic.mypy` plugin.

### Example Code

```Python
import pydantic

def get_my_custom_validator(field_name: str) -> classmethod:
    @pydantic.validator(field_name, allow_reuse=True)
    def my_custom_validator(cls, v: int) -> int:
        return v

    return my_custom_validator

def foo():
    class MyModel(pydantic.BaseModel):
        number: int
        custom_validator = get_my_custom_validator("number")
        # custom_validator: classmethod = get_my_custom_validator("number")  # does not crash

    pass
```
