Create User GET Request Handler

[IvanA673]

Description
Create the GET HTTP Request API Route Handler to get an instance of a user. If you need an example of a GET handler with Prisma, look under resources in Sprint 1 Google doc. You can expect to the data to be in the request body and it will be coming from a form submission. Research and implement querying the database with a specific field (an email) utilizing Prisma.

Steps:

• Create a new folder under api named "user". Within that folder create a new route.ts file.
• Within that new route.ts file, create the GET function to get the data of a user from the database.
