Sort resources alphabetically in README

[Khalilsqu]

Description

This PR introduces alphabetical sorting for all resources, categories, and subcategories in the README to improve readability and navigation.

Key Changes:

• Alphabetical Order: Resources are now sorted case-insensitively by name at all levels (categories, subcategories, nested resources).
• TOC Consistency: The table of contents now reflects the sorted structure.
• Special Handling: Maintained table format for "Software and Tools" while sorting entries.
• Recursive Sorting: Implemented hierarchical sorting for nested subcategories.

Why This Matters

• 🔍 Easier Navigation: Users can quickly locate resources without scanning entire sections.
• 🧩 Consistency: Standardizes the presentation of 300+ resources.
• 🤖 Automation: Ensures future additions will follow alphabetical order.

Technical Details

• Used sorted(resources, key=lambda x: x['name'].lower()) for case-insensitive sorting.
• Updated process_subcategory and generate_toc functions to handle recursion.
• Verified sorting integrity across all 8 main categories and 32 subcategories.

Note
This change does not affect existing URLs or resource metadata – only the display order is modified.
