[issue46757] dataclasses should define an empty __post_init__

Good thinking.  Would it make sense to add to the documentation as well that the __post_init__ methods aren't collected, and you should call super's __post_init__ if there is one using something like

        if hasattr(super(), "__post_init__"):
            super().__post_init__()

Noting this will make it easier to point to the docs if someone wonders when they see code like this.
