Fix: docs sidebar anchors

[er-mene]

Summary

Fixed a systematic offset in the Table of Contents (TOC) within the "Browser Crawler Configuration" documentation. The issue caused sidebar links to navigate to incorrect sections due to automatic anchor ID mismatches. By adding explicit IDs to the headers, the navigation is now stable and accurate.

Fixes: None (Internal documentation improvement)

List of files changed and why

docs/md_v2/core/browser-crawler-config.md: Added explicit anchor IDs (e.g., {: #browser-config-key-fields }) to several headers to resolve cascading TOC displacement and ensure consistent deep-linking.

How Has This Been Tested?

-[x] Local Build: Ran mkdocs serve locally to compile the documentation and verify the rendering.
-[x] Browser Verification: Tested the navigation. While there is a minor visual offset when scrolling upwards (likely due to the site's sticky header overlap, which is a global CSS behavior), the logic is now correct: each TOC link now maps to the intended section instead of being displaced to unrelated parts of the document.
