fix(docs): align prisma init config examples

[AmanVarshney01]

Summary

• update Prisma ORM quickstart and add-to-existing generated prisma.config.ts snippets to match current prisma init output
• replace defineConfig, env examples with defineConfig plus process.env["DATABASE_URL"]
• remove the obsolete extra MongoDB dotenv step because current prisma init already generates it

Root cause

The docs showed an older generated prisma.config.ts shape, while Prisma 7.8.0 now generates comments, imports only defineConfig, and reads DATABASE_URL from process.env.

Validation

• npx --yes prisma@latest init --datasource-provider postgresql --output ../generated/prisma
• npx --yes prisma@latest init --datasource-provider mongodb --output ../generated/prisma
• npx --yes prisma@latest init --datasource-provider sqlite --output ../generated/prisma
• rg -n 'defineConfig, env|url: env\\("DATABASE_URL"\\)|engine: "classic"|Add dotenvtoprisma.config.ts' apps/docs/content/docs/\\(index\\)/prisma-orm -g '*.mdx' -S\n- cd apps/docs && pnpm exec cspell $(git -C ../.. diff --name-only HEAD~1 -- apps/docs/content/docs/\\(index\\)/prisma-orm/\'*.mdx\' | sed 's#^apps/docs/##') --show-context\n- git diff --check\n\nFixes prisma init ... command generates different output, than what is shown in the docs #7818\n

Summary by CodeRabbit

• Documentation
  • Updated configuration examples across all database guides (PostgreSQL, MySQL, MongoDB, CockroachDB, PlanetScale, Prisma Postgres, SQL Server, SQLite) to reflect current environment variable configuration standards. Updated snippets now include prerequisite installation notes where applicable.

Walkthrough

Sixteen documentation files across Prisma's ORM database guides are synchronized with the current Prisma CLI initialization output. All prisma.config.ts code examples now remove the env() helper import and use direct process.env["DATABASE_URL"] access, with clarifying comments about required prisma and dotenv dependencies.

Changes

Prisma Config Documentation Examples

Layer / File(s)	Summary
Add-to-existing-project guides: env() to process.env apps/docs/content/docs/(index)/prisma-orm/add-to-existing-project/cockroachdb.mdx, mongodb.mdx, mysql.mdx, planetscale.mdx, postgresql.mdx, prisma-postgres.mdx, sql-server.mdx, sqlite.mdx	Eight guides update their generated prisma.config.ts snippets to remove the env import from prisma/config and replace env("DATABASE_URL") with process.env["DATABASE_URL"]. MongoDB additionally removes the deprecated engine: "classic" field and clarifies the dotenv/config side-effect import pattern. All guides now include comments documenting the required prisma and dotenv dev dependencies.
Quickstart guides: env() to process.env apps/docs/content/docs/(index)/prisma-orm/quickstart/cockroachdb.mdx, mongodb.mdx, mysql.mdx, planetscale.mdx, postgresql.mdx, prisma-postgres.mdx, sql-server.mdx, sqlite.mdx	Eight quickstart guides apply the same config example updates: removing env from imports and switching to direct process.env["DATABASE_URL"] access. MongoDB quickstart also removes engine: "classic" and adds explicit dotenv/config import. Generated-file header comments and dependency notes are added or clarified across all guides.
