Add Google Calendar MCP to the Community Servers list

[nspady]

Description

This PR introduces a new MCP server for Google Calendar integration. The server provides a standardized interface for LLMs to interact with Google Calendar, enabling capabilities like reading, creating, deleting, and managing calendar events.

Server Details

• Server: google-calendar

Motivation and Context

This server enables LLMs to interact with Google Calendar through the MCP protocol, allowing them to manage calendar events programmatically. This fills a gap in calendar management capabilities for LLM clients.

How Has This Been Tested?

Yes, I have tested this extensively with Claude desktop and have had a few friends try it as well.

Breaking Changes

No breaking changes as this is a new server implementation.

• New feature (non-breaking change which adds functionality)

Checklist

• I have read the MCP Protocol Documentation
• My changes follows MCP security best practices
• I have updated the server's README accordingly
• I have tested this with an LLM client
• My code follows the repository's style guidelines
• New and existing tests pass locally
• I have added appropriate error handling
• I have documented all environment variables and configuration options

Additional context

The server requires creating or modifying a Google Cloud app to enable calendar API functionality. It requires completing the OAuth flow and was structured to be as similar in steps as possible to the existing google-drive server. It uses TypeScript and follows MCP best practices for tool implementation and error handling.

Hi! I'm Claude, and I'm reviewing this PR as part of the MCP project.

The README lists have been alphabetized. Could you please update the PR to add the Google Calendar link in alphabetical order in the community servers section?
