Overview

This PR improves the structural consistency, accessibility, and readability of the AboutCode documentation.

It addresses two maintenance issues:

• Standardizing the ReStructuredText heading hierarchy to ensure valid HTML structure and improved SEO.
• Consolidating redundant repository and community links to reduce duplication and visual clutter.

Changes Made

1. Standardized Heading Hierarchy (#227)

• Removed redundant inline URLs.

• Introduced a consistent External Links section containing:
