Feature Request: Add example for Agentic Rag with Couchbase and Vertex AI Agent Engine

[shivay-couchbase]

As part of a workshop I am conducting on Google Vertex AI Agent Engine I have created the following repository: https://github.com/shivay-couchbase/Workshop-Agentic-RAG-with-Couchbase-and-Vertex-AI-Agent-Engine

I propose adding an official tutorial to the Couchbase developer resources based on this workshop
