Add Agenta - Open-source LLMOps platform

[mmabrouk]

Hi!

I'd like to add Agenta to the LLM, Gen-AI, and Agents section.

What is Agenta?

Agenta is an open-source LLMOps platform that helps developers:

• 🔧 Prompt Engineering - Collaborative prompt management and versioning
• 📊 LLM Evaluation - Automated and manual evaluation workflows
• 👁️ Observability - Monitor and debug LLM applications in production

Changes Made

• Added Agenta logo to static/image/logos/agenta.png
• Added Agenta card to the "LLM, Gen-AI, and Agents" section
• Follows the existing Bootstrap card format used by other frameworks
• Links to both website (agenta.ai) and GitHub repository

Why Include It?

• ✅ Python-based - Built with Python, fits perfectly with other Python LLM frameworks
• ✅ Open Source - MIT licensed with active development
• ✅ Production Ready - Used by teams building LLM applications
• ✅ Complements Existing Tools - Works alongside LangChain, LlamaIndex, etc.

The addition fits naturally in the existing section alongside other LLM development and orchestration frameworks.

Thanks for maintaining this awesome resource!
