Using `mock.patch` as a decorator doesn't properly forward the underlying function signature (even with a `new=` argument)

The following seems to type check fine (both mypy and pyright) even though it should not (I would hope):

```py
from unittest.mock import Mock, patch

@patch("sys.exit", new=Mock())
def f(i: int) -> None:
    ...

f("a")
```

Tried with `types-mock==5.0.0.6`.
