feat: Add audit for broken content fragment requests

[holtvogt]

This PR introduces two new audits to monitor and analyze content fragment health on AEM:

What's New

• CDN Content Fragment 404 Audit (cdn-content-fragment-404): Monitors CDN logs hourly to identify content fragment requests that return 404 errors, using Athena queries to aggregate and export the data to S3 for further analysis and reporting.
• Content Fragment Broken Links Audit (content-fragment-broken-links): Analyzes broken content fragment paths discovered in CDN logs on a daily basis, and intelligently suggests repair actions through a multi-step workflow that applies various strategies like republishing, locale fallbacks, and similar path matching.

Use Case

Health monitoring for Content Fragments on AEM Sites: Automatically detect broken content fragment references across AEM Sites by monitoring CDN traffic patterns, identifying 404 errors, and providing actionable repair suggestions to maintain content availability and user experience.

• The removeDoubleSlashes function incorrectly removes one slash from protocol schemes. The expected result should preserve the protocol format 'http://example.com/path' rather than converting to 'http:/example.com/path'.
