Summary: Github tests caught another too-new-to-use feature in our Python code: you cannot directly subscript builtin containers like `dict` until 3.9. In this case since there's no runtime need for the annotation, we can use `from __future__ import annotations` to work around the problem. Differential Revision: D56821982
