AWS documentdb documentation change
Summary
Removed the entire documentation page for the $addFields aggregation stage in Amazon DocumentDB, including examples, code samples, and usage instructions.
Security assessment
The change completely removes documentation content without any mention of security vulnerabilities, patches, or security-related fixes. This appears to be a routine documentation cleanup or restructuring, not related to addressing any security issue. The removed content was standard feature documentation with no security warnings or security-specific content.
