Fix missing Real-World Examples and Experimental RL Optimization sections on tutorials page (#8982)

* Add Real-World Examples section to tutorials index page

The tutorials index page was missing the Real-World Examples section,
which includes 6 practical application tutorials:
- Generating llms.txt
- Email Information Extraction
- Memory-Enabled ReAct Agents with Mem0
- Financial Analysis with Yahoo Finance
- Automated Code Generation from Documentation
- Building a Creative Text-Based AI Game

This ensures all tutorial categories are visible on the main tutorials page.

* Add Experimental RL Optimization section and reorganize tutorials

- Added missing Experimental RL Optimization section with 2 tutorials:
  - RL for Privacy-Conscious Delegation
  - RL for Multi-Hop Research

- Moved Real-World Examples section to appear after Tools, Development,
  and Deployment section for better organization

This ensures all tutorial categories are properly listed and organized
on the main tutorials page.
