Stubgen moves non default keyword-only argument in front of *

[khameeteman]

Bug Report

Stubgen generates incorre stubs when a non default keyword-only argument is positioned after the asterix symbol in the signature.

To Reproduce

1. Create a function:

def func(*, non_default_kwarg: bool, default_kwarg: bool = True):
    pass

2. Generate stubs

Expected Behavior

def func(*, non_default_kwarg: bool, default_kwarg: bool=...) -> Any: ...

Actual Behavior

def func(non_default_kwarg: bool, *, default_kwarg: bool=...) -> Any: ...
