Type checking using Ty

[armanddidierjean]

Description

Summary

Typecheck the codebase using ty in addition to mypy.

Ty was able to detect multiples type related issues in our current codebase that are fixed by this pull request. This pull request will also allow developpers to use Ty to typecheck their code in realtime during development.

Mypy is still able to detect some issues that Ty don't catch, and there are still a few bugs in Ty. The idea of this pull request is thus to run both typecheckers in the CI

Based on aeecleclair#954
