Hanami 2.3 CRUD

I have been running into places where the 2.3 examples falls short. AKA when I want to update or delete.

I have added that type of behavior into our Princeton application, in our user repo. Most recently I dug up how to delete objects.

I thought it would be really nice if the introductory example showed Update. I took a stab at adding in update to the tutorial.

If it doesn’t make it into the documentation I thought it might still help some folks if I linked the information in the forum.

Cheers!
