stubgen seems not able to handle a property deleter

[ktns]

Bug Report

When I feed stubgen with a class with a deleter method of a property, it seems to ignore the decorator.

To Reproduce

class Foo:
    @property
    def bar(self)->int:
        return 42

    @bar.setter
    def bar(self, int) -> None:
        pass

    @bar.deleter
    def bar(self) -> None:
        pass

Expected Behavior

class Foo:
    @property
    def bar(self) -> int: ...
    @bar.setter
    def bar(self, int) -> None: ...
    @bar.deleter
    def bar(self) -> None: ...

Actual Behavior

class Foo:
    @property
    def bar(self) -> int: ...
    @bar.setter
    def bar(self, int) -> None: ...
    def bar(self) -> None: ...
