Merge bitcoin/bitcoin#28725: test: refactor: use built-in collection types for type hints (Python 3.9 / PEP 585)

Pull request description:

  With Python 3.9 / [PEP 585](https://peps.python.org/pep-0585/), [type hinting has become a little less awkward](https://docs.python.org/3.9/whatsnew/3.9.html#type-hinting-generics-in-standard-collections), 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 (see  https://peps.python.org/pep-0585/#implementation for the full list).

  This PR applies the replacement for all Python scripts (i.e. in the contrib and test folders) for the basic types, i.e.:

  - typing.Dict -> dict
  - typing.List -> list
  - typing.Set  -> set
  - typing.Tuple -> tuple

  For an additional check, I ran mypy 1.6.1 on both master and the PR branch via
  ```
  $ mypy --ignore-missing-imports --explicit-package-bases $(git ls-files "*.py")
  ```
  and verified that the output is identical -- (from the 22 identified problems, most look like false-positives, it's probably worth it to go deeper here and address them in a follow-up though).
