Update Showcase Project

[wvmitchell]

Project to be updated: Showcase

Summary of changes needed:

• Currently, the rubric suggests that students will need to demonstrate an understanding of class-based components
• The rubric needs to be updated to expect the use of functional components, and the use of the useState and useEffect hooks to manage state and parse updates from the API.
• Update rubrics to use the Yes, Not Yet, Wow scale that was piloted on M1 projects. Use M1/M2 projects as a guide for consistency.
