[Invoke] Replace `List`, `Dict`, `Tuple` with the Python >= 3.9 equivalents

[amenasria]

What does this PR do?

This PR replaces:

• List -> list
• Dict -> dict
• Tuple -> tuple

Motivation

Clearer code. We're using Python >= 3.9, meaning we don't need typing for those: https://mypy.readthedocs.io/en/stable/builtin_types.html#generic-types

I remember trying this earlier, and seeing this fail because some parts of the CI use Python < 3.9, but maybe that has changed?

Cries in cringe, some of the tests are using Python 3.7 💀

We'll see 😳
