File: AWSCloudFormation/latest/TemplateReference/aws-resource-autoscaling-scalingpolicy.md

Summary

Reformatted JSON/YAML examples to use compact syntax without changing functionality

Security assessment

Changes are purely formatting/whitespace adjustments to CloudFormation examples. No security-related parameters, configurations or warnings were added/modified. Security group references (InstanceSecurityGroup) and monitoring settings remain unchanged from previous examples.
