AWS documentdb documentation change
Summary
Entire documentation page for the $dateSubtract aggregation operator has been removed.
Security assessment
The change removes all content from the documentation page without any mention of security vulnerabilities, patches, or security-related fixes. This appears to be a routine documentation cleanup or restructuring, possibly moving content elsewhere. There is no evidence in the diff of addressing a security issue.
