fix(docs): use local TypeScript compiler in package manager tabs

[futurehua]

Summary

• Prevent package-manager tabs from translating npx tsc into pnpm dlx tsc or yarn dlx tsc.
• Use the locally installed TypeScript compiler through pnpm tsc and yarn tsc.
• Preserve the existing npm, Bun, and unrelated dlx conversions.

Fixes #8064.

Why

The documentation installs typescript before running tsc, but npm-to-yarn currently converts npx tsc --init to:

• pnpm dlx tsc --init
• yarn dlx tsc --init

Both dlx commands fetch the package named tsc from the registry instead of using the binary from the locally installed typescript package. That registry package is an unrelated deprecated placeholder, so the generated quickstart commands fail.

The fix is applied at the shared command-conversion boundary so every npm code block containing npx tsc produces the correct pnpm and Yarn commands.

Validation

• Regenerated the Fumadocs sources.
• Verified the generated commands:
  • npm: npx tsc --init
  • pnpm: pnpm tsc --init
  • yarn: yarn tsc --init
  • Bun: bunx tsc --init
• pnpm exec oxfmt --check apps/docs/source.config.ts
• pnpm exec oxlint apps/docs/source.config.ts
• pnpm --filter docs run types:check

Summary by CodeRabbit

• Bug Fixes
  • Updated package manager command conversion so TypeScript compiler commands are correctly formatted for pnpm and Yarn documentation examples.
