test: use built-in collection types for type hints (Python 3.9 / PEP 585)

Since Python 3.9, type hinting has become a little less awkward, as for
collection types one doesn't need to import the corresponding
capitalized types (`Dict`, `List`, `Set`, `Tuple`, ...) anymore, but can
use the built-in types directly. [1] [2]
This commit applies the replacement for all Python scripts (i.e. in the
contrib and test folders) for the basic types:
    - typing.Dict  -> dict
    - typing.List  -> list
    - typing.Set   -> set
    - typing.Tuple -> tuple
