Subject: [PATCH] Fix stubtest's tests to work with the latest
 typing_extensions release (#16588)

Stubtest's tests will start failing when `typing_extensions==4.9.0`
comes out, due to some new `ClassVar`s on `typing_extensions.TypedDict`.
This PR fixes that.

Fixes https://github.com/python/typing_extensions/issues/309
