typing: Gst: Update stubs to 1.28.2

Those stubs are generated in an Ubuntu 26.04 docker which now has everything needed for GStreamer.

@bryanforbes GStreamer overrides have class Iterator(GObject.GBoxed, typing.Generic[T]):. But it seems stubs are not importing typing module anymore.

But it seems stubs are not importing typing module anymore.

The generator uses import tracking now, so symbols are imported directly. The issue is that for objects that have GObject introspection information, the bases aren't looked at. I'll work on modifying the generator to inspect that.

[bryanforbes]

The overrides should be using collection.abc.Iterator since typing.Iterator has been deprecated since 3.9. It would also be good if the overrides used typing_extensions.TypeVar so the generic can have a default (T = TypeVar('T', default=Any)).

[bryanforbes]

I have a solution that I worked up today to build the base class list for the stubs based on the MRO. I need to run a few more tests in the morning, but it’s far more robust and retains the classes set up by overrides, including Generic and its type arguments.

[bryanforbes]

I merged my solution and the other gstreamer PR that generates from 1.26. You'll want to rebase on master and regenerate the gstreamer stubs.

Thanks! Stubs regenerated and seems good now.

BTW, I noticed another possible regression (not related to gst), for boxed types we generate:

    @staticmethod
    def __new__(cls: type[Self]) -> Self: ...

But pylance complains: "Self" is not valid in this context. It seems it's not allowed to use Self with staticmethod. Technically new is not a classmethod.

That's on my list of things to address. There are definitely places where PyGObject are incorrectly using Self, but I think the generator is adding those to other methods as well.
