use HTTP instead of WebSockets in neon-prisma routes

[nikolasburk]

The new addition of Prisma ORM with Neon uses the WebSocket connection of the Neon Serverless Driver while the one with Drizzle uses the HTTP connection.

This PR updates this and makes Prisma ORM also use HTTP so that the comparison is based on using the same protocols.

I've left the instantiation of the previous WebSocket connection around in comments as additional context.

Hey @leerob, do you think you could merge this or is there anything you think that needs to be changed?
