import-checker: allow symbol imports from typing module...

import-checker: allow symbol imports from typing module As we add typing annotations, we'll want to use a lot of symbols from the `typing` module. Typing `typing` all the time will be annoying. Let's allow symbol imports from this module. While I was here, I changed some comments from "whitelist" to "allow list" as the former is non-inclusive terminology.
