AWS documentdb documentation change
Summary
Entire documentation file for the $max aggregation stage was removed, including examples in MongoDB Shell, Node.js, and Python
Security assessment
This change removes documentation for a MongoDB aggregation operator ($max) but provides no indication of security issues. The removed content was standard documentation with code examples and no security warnings. This appears to be documentation reorganization rather than security-related changes.
