AWS documentdb documentation change
Summary
Added new documentation page for the $anyElementTrue operator in Amazon DocumentDB, including syntax, parameters, MongoDB shell examples, and code examples in Node.js and Python with connection strings
Security assessment
This change adds routine documentation for a MongoDB aggregation operator ($anyElementTrue) with standard usage examples. The code examples include TLS connection parameters (tls=true, tlsCAFile=global-bundle.pem) which are standard security practices for DocumentDB connections, but this is not introducing new security documentation - it's showing standard secure connection patterns that already exist in other documentation. There is no evidence this addresses a specific security vulnerability or incident.
