docs: Add Google Drive MCP Extension tutorial

[EbonyLouis]

This PR adds a tutorial for integrating the Google Drive MCP Server as a Goose extension. This allows users to list, read, and search Google Drive files using Goose.

Changes Made

✅ New Tutorial Added:

• File: documentation/docs/tutorials/google-drive-mcp.md
• Google Cloud Setup (OAuth credentials, enabling API access)
• Installation & Configuration (Goose CLI & Goose Desktop setup)
• Step-by-step instructions for adding the extension manually
• Example usage with Goose AI for searching and summarizing Google Drive files

✅ Example Scenario Included:

• In this example, I’ll use Goose to quickly gather and summarize important information for my upcoming marketing budget review meeting in 30 minutes. I’ll ask Goose to find relevant documents from my Google Drive, summarize Q1 performance, highlight critical decisions on marketing automation and video production, and identify any outstanding action items from our last meeting.
