Schema: Add Delete Model and Duplicate Model Buttons

[zcolah]

Problem
Users have reported that they go to the Info Tab when they want to delete or duplicate a model. However they are unable to find any option that allows them to do the same.

Describe the solution you'd like
We have added two buttons: a Delete Button, and a Duplicate Model button to the model details section in the Info Tab to help solve for this problem. See the Figma User flows here: https://www.figma.com/file/jeRhgXqNsP7Bmd2YoQLA4z/Schema-App?type=design&node-id=2303%3A227924&mode=design&t=GbfNzWvfT04t8E3o-1

Currently these actions exist in the model flyout. Do we plan on leaving them there or should those be removed?

These actions should remain in the fly out.
