[docs] [issue35001] ImportFrom level cannot be optional

[Anthony Sottile]

Anthony Sottile <asottile at umich.edu> added the comment:

Hmmm, I don't think mypy has an annotation for "sometimes has an attribute" -- `Optional[T]` is `Union[T, None]` (why I tried `None`).

But you're right, `FromImport` is constructable without a `level` -- it seems to behave as `level=0` (I guess as expected!)
