[Typing-sig] PEP 692: Using TypedDict for more precise **kwargs typing

Adding support for more precise **kwargs (consisting of different types) typing using TypedDict has been a very desired feature in python community [1]. The feature proposal has been discussed both on the mailing list and at a typing meetup and received positive feedback. I've submitted PEP 692 that aims to add support for more precise **kwargs typing. The PR is available at https://github.com/python/peps/pull/2620 And the preview at https://pep-previews--2620.org.readthedocs.build/pep-0692/ - **kwargs can consist of different types - A new syntax `def foo(**kwargs: **Movie): ...` that enables the feature is introduced Please let me know what you think about it.
