[Feature Request]: Add AG2 community integration example to docs/examples

[VasiliyRad]

What needs to be done?

Add a "Community Integrations" section to examples.md with a working AG2 (autogen.tools.experimental.Crawl4AITool) snippet, and a pointer in quickstart.md under "Next Steps" so users can discover it naturally.

What problem does this solve?

AG2 has a first-class Crawl4AITool built into autogen.tools.experimental with its own official documentation — but Crawl4AI's own docs make no mention of it. Users building multi-agent pipelines with AG2 have no obvious path to discover this integration, even though it works out of the box.

Target users/beneficiaries

AG2/AutoGen developers (400,000+ monthly downloads, 20,000+ community members) who want to use Crawl4AI inside multi-agent workflows for web scraping, RAG pipelines, and data extraction tasks.

Current alternatives/workarounds

Users can find the integration via AG2's own docs (docs.ag2.ai), but only if they already know to look there. There is no cross-reference from Crawl4AI's side, so discoverability is essentially zero for Crawl4AI-first users.

Proposed approach

This is a pure documentation change — no code or maintenance burden on the Crawl4AI team. The integration is owned and maintained by AG2. PR #1756 already implements the full change across two files (examples.md and quickstart.md) and is ready to review. The success metric is simple: AG2 users landing on Crawl4AI docs can find a working example without leaving the site.

From my point of view, this is exactly the sort of docs-only integration note that can deliver real value without creating much maintenance burden. If AG2 already owns the integration and the example works today, Crawl4AI users benefit simply from discoverability.

Cross-linking working ecosystem integrations is often one of the highest leverage things docs can do for agent frameworks.
