docs(docs): align quickstart prisma.config.ts with actual prisma init output

[morgan-coded]

What

The quickstart guides show the generated prisma.config.ts as:

import "dotenv/config";
import { defineConfig, env } from "prisma/config";
...
  datasource: { url: env("DATABASE_URL") }

But prisma init (standard npm/pnpm/yarn, i.e. the non-Bun runtime) actually
generates:

import "dotenv/config";
import { defineConfig } from "prisma/config";
...
  datasource: { url: process.env["DATABASE_URL"] }

The env() import/accessor is only emitted on the Bun runtime branch. In
packages/cli/src/Init.ts, defaultConfig picks the template with
runtime: isBun ? 'bun' : 'other', and the 'other' branch uses
import { defineConfig } + process.env["DATABASE_URL"]. The datasource
provider and --db flag don't change this. So the docs were incorrect for the
standard flow every quickstart describes (they all install via npm + dotenv).

Reported in #7818.

Change

Update the prisma.config.ts example to match the actual non-Bun output on the
7 single-block quickstarts: postgresql, prisma-postgres, mysql, sqlite,
sql-server, cockroachdb, planetscale.

mongodb is intentionally left out — it presents a different two-step
"generated, then add dotenv" narrative with engine: "classic", and should be
reviewed separately.

Testing

• pnpm run lint:spellcheck — passes.
• Verified the replacement against prisma/prisma packages/cli/src/Init.ts
  (defaultConfig, runtime: 'other' branch).

Closes #7818

Summary by CodeRabbit

• Documentation

Walkthrough

This PR updates documentation quickstart guides for seven database providers to align their example prisma.config.ts code blocks with the actual output generated by the prisma init command. The change removes the env helper import and replaces env("DATABASE_URL") with direct process.env["DATABASE_URL"] access.
