AWS documentdb documentation change
Summary
Entire documentation page for the $addToSet operator was removed, including all examples, code samples, and usage instructions.
Security assessment
This change removes documentation content entirely but does not indicate any security vulnerability or weakness. The removal includes code examples showing TLS connections with CA certificates, but this appears to be routine documentation cleanup or restructuring rather than a security-related change. No security issues are mentioned in the diff.
