What does this PR do? What is the motivation?

Documents the resource.local_cache_hit attribute added to the RUM iOS SDK (dd-sdk-ios#3074, RUM-17207):

  • Adds it to the iOS Data Collected reference table (resource.local_cache_hit, boolean; only sent as true, never false).
  • Adds a note under Advanced Configuration > Automatically track network requests explaining the signal and that it's only available in registered-delegate instrumentation mode (not automatic/completion-handler swizzling).

AI assistance

Used Claude Code to research the existing per-SDK data_collected and advanced_config reference conventions and apply the doc changes.

Additional notes

No shared/common cross-SDK page exists yet for resource cache-status concepts (checked); this follows the existing per-platform data_collected table and advanced_config notes conventions. A dedicated cross-platform page (similar to Browser's "Monitoring Resource Performance") could make sense later once Android ships its own cache-hit signal.
