[Docs]: MetaGPT integration coverage

### 📘 Current State of Documentation

AgentOps is integrated in the MetaGPT repo, but it's not documented in our docs: https://github.com/geekan/MetaGPT

Create a page in the docs that shows an example MetaGPT run + screenshots and how to run a MetaGPT agent with AgentOps
