Comparing timestamps returned by the API with naive datetime objects (without timezone information) will raise an error. Add `tzinfo=datetime.timezone.utc` to your datetime instance.

Moves `Github.get_app()` called without `slug` parameter into `GithubIntegration`, because it needs an `AppAuth`,
and we collect all such endpoints there. Calling `Github.get_app()` without `slug` parameter is now deprecated.
Replaces `datetime.utcnow()` with `datetime.now(timezone.utc)`, as it is deprecated in Python 3.12.
