Improve yaml/constructor.pyi types

When updating mypy to 1.11.0 in typeddjango/django-stubs#2269 I noticed this:

=========================== short test summary info ============================
```

This happens because `UnsafeConstructor` has unsafe method overrides and new mypy detects this.

So, I added just some simple annotations so it can detect it now as well.
