AWS documentdb documentation change
Summary
Entire documentation page for the $replaceWith aggregation operator has been removed, including syntax, parameters, examples in MongoDB Shell, Node.js, and Python, and all related content.
Security assessment
This change removes documentation for a specific aggregation operator ($replaceWith) but does not contain any evidence of addressing a security vulnerability, weakness, or incident. The removal appears to be a documentation restructuring or deprecation of content rather than a security-related fix. No security implications are mentioned in the removed content.
