docs: make the browser quickstart copy-paste complete

[MagMueller]

What changed

• use the API V4 SDK namespace in both browser-management examples
• install Playwright before importing it
• give Puppeteer its own puppeteer-core install tab
• regenerate both llms-full.txt mirrors

Why

The Browser Infrastructure quickstart said API V4 but imported the V3 SDK. It also installed only browser-use-sdk, then imported Playwright in the next section. A fresh Python environment reproduces ModuleNotFoundError: No module named 'playwright'.

Validation

• npx --yes mintlify@latest broken-links
• Python: 61 tests passed
• TypeScript: 147 tests passed
• TypeScript typecheck and CJS/ESM/DTS build passed
• fresh Python install: documented imports pass with the new install command
• fresh Node install: browser-use-sdk/v4 and playwright imports pass
• generated docs are reproducible and git diff --check is clean

No API behavior changes.

Summary by cubic

Fixes the browser quickstart so the install commands and code examples actually run: it now uses the V4 SDK namespace and installs Playwright, which was missing and caused ModuleNotFoundError in a fresh Python environment.

• Adds a separate Puppeteer install tab for TypeScript users.
• Regenerates both llms-full.txt mirrors to match the quickstart.
• No API behavior changes.
