docs: add naxytra MCP discovery note

[naxytra]

Summary

• Adds a public MCP discovery note to the CrewAI MCP DSL integration guide.
• Points readers to the canonical naxytra discovery index, A2A card, and live MCP endpoint.

Why

• CrewAI users integrating external MCP servers should have a concrete public example to reference.
• This keeps the docs aligned with the live public entry surfaces without exposing private code.
