[DOCS]: Official Framework Integration Guides

### Enhancement hasn't been filed before.

- [x] I have verified this enhancement I'm about to request hasn't been suggested before.

### Describe the enhancement you want to request

### The problem

There is no official guide to integrate Drizzle ORM with popular frameworks like **NestJS**. As a developer trying to use Drizzle in a NestJS project, I spent hours searching and couldn't find a clear, official, and straightforward implementation. Everything I found was either outdated, incomplete, or required a lot of boilerplate just to get started.

This is a real barrier to adoption.

### What I'm requesting

Add an official **Frameworks** section to the Drizzle documentation, exactly like **Prisma** already does:
https://www.prisma.io/docs/guides/frameworks/nestjs

Prisma has dedicated guides for: Next.js, Astro, Nuxt, SvelteKit, SolidStart, React Router 7, TanStack Start, **NestJS**, Hono, Elysia — each one with a clear, step-by-step setup.

Drizzle should have the same. At minimum, starting with **NestJS**, which is one of the most widely used Node.js frameworks.

Each guide should cover:
- Installing and configuring Drizzle within the framework
- Exposing the Drizzle instance using the framework's patterns (e.g., NestJS modules and providers)
- A minimal working example with a real database

### Why this matters

When a developer is choosing between Prisma and Drizzle, official framework guides are a deciding factor. Prisma has them. Drizzle doesn't. That gap directly affects adoption.

No repository file, test, or documentation entry point is identified in the issue. Start by locating the existing Drizzle documentation structure and reviewing the linked Prisma NestJS guide. Done means an official NestJS guide covers installation, configuration, framework modules and providers, and a minimal real-database example.
