Improve template descriptions in OpenAI_and_LLMs section

[Samra-Ishaq]

What this PR does

Expands overly brief descriptions for 5 templates in the OpenAI_and_LLMs section, which previously read as one-liners like "Basic AI chat agent." — inconsistent with the more detailed descriptions used throughout the rest of the README.

Templates updated

• AI agent chat
• Advanced AI Demo (Presented at AI Developers N8n 2 #14 meetup)
• AI agent that can scrape webpages
• AI Crew to Automate Fundamental Stock Analysis - Q&A Workflow
• AI Customer feedback sentiment analysis

Why

These are among the most-used categories (17 templates), so clearer descriptions help users quickly find the right template without opening each JSON file.

Also added a "My Contribution" section documenting this change for transparency.
