[BUG] type annotations for optional parameters

[alexdrydew]

Observed behavior

Type annotations of optional parameters are not propagated to __init__ methods of the attrs generated classes, which leads to incrorect stubs and failing mypy.

Expected behavior

Every Optional[...] or Union[..., None] parameter should have a correct annotation in the __init__ method
