Added Prisma Postgres guide to docs/integrations/databases/

[aidankmcalister]

🔎 Previews:

• New Prisma Postgres integration guide for Clerk
• Step-by-step guide for setting up Clerk + Prisma Postgres in Next.js
• https://clerk.com/docs/pr/fork-aidankmcalister-prisma-postgres-adde-ec58a4/integrations/databases/prisma-postgres

What does this solve?

• Missing Documentation: There was no existing guide for integrating Clerk with Prisma Postgres
• Developer Need: Developers using Prisma Postgres needed a clear tutorial on how to integrate with Clerk authentication
• Complete Integration: Provides a full example of Clerk + Prisma Postgres + Prisma ORM setup from scratch

What changed?

• New File: Created docs/integrations/databases/prisma-postgres.mdx as a complete new guide
• Simple Schema: Uses a basic UserMessage model to demonstrate Clerk + Prisma integration
• Server Actions: Shows how to use Clerk's auth() helper with Prisma for database operations
• Complete Tutorial: Includes project setup, middleware configuration, schema definition, and UI implementation
• Clear Structure: Follows a logical flow from setup to running the application

Thank you Aidan for writing this guide, I'll run through it now! I've added a preview link if you'd like to see how it looks on the docs site.

I'll have a final review here once Aidan addresses Nick's comments :)

Thank you for taking a look at this!

@alexisintech, I've implemented the changes requested by @NWylynko and made additional updates to align with the latest version of Prisma ORM (v6.16).

One of the changes I made was:

  generator client {
    // Change the provider from "prisma-client-js" to "prisma-client"
    provider = "prisma-client"
    output   = "../app/generated/prisma"
  }

I'm not sure about the proper title for it, but is there a flag that can indicate to remove this line and add this one? Similar to how other docs and GitHub use red for removal and green for addition.
