AWS documentdb documentation change
Summary
Entire documentation page for the $mergeObjects operator has been removed, including all examples, code samples, and explanatory content
Security assessment
This change removes documentation for a MongoDB aggregation operator ($mergeObjects) but does not contain any evidence of addressing a security vulnerability, weakness, or incident. The removal appears to be a routine documentation cleanup or reorganization, possibly moving content to another location. No security implications are evident from the removal of this operator documentation.
