Fix broken Table of Contents links in README for PyPI

[VeeshaFatima890]

This PR updates the README Table of Contents so that navigation works properly on PyPI:

• Fixed links for "Advanced API" and "Expanded Examples" by replacing relative anchors with absolute GitHub URLs.
• Synced TOC structure with the latest README (added "Automatic Driver and Browser Management", "Examples", and "Release Workflow").and Ensures that all sections (e.g., Advanced API, Tutorials, Examples) link correctly
  to their respective headings, improving navigation and readability.

Closes #493.

Hope this helps improve the project. Please let me know if you’d like me to adjust anything.
