PR Summary

Documentation fix to correct an inaccurate comment about property masking in packages/browser/src/types.ts. The change clarifies that mask_personal_data_properties masks advertising IDs (gclid, fbclid) rather than UTM parameters.

• Updated configuration documentation in types.ts to accurately describe the masking behavior for advertising IDs
• Added helpful examples to improve clarity of the masking functionality
• Fixed misleading comment that incorrectly claimed UTM parameter masking
