Sara RobinsonandCopybara-Service 32f9f92042 chore: Add GitHub Action check to run mypy
Merge https://github.com/google/adk-python/pull/4276

This adds 2 mypy GitHub Actions checks:

* `mypy.yml` runs mypy on every PR. This will list all errors, so it shouldn't block until errors are resolved.
* `mypy-new-errors.yml` compares the PR branch to `main` to ensure no new mypy errors are introduced. This check can be made blocking now and can be removed once all errors are resolved in favor of `mypy.yml`.
