AWS autoscaling documentation change
Summary
Updated documentation to consistently use 'Amazon EC2 Auto Scaling group' instead of 'Auto Scaling group' for service name accuracy. Adjusted console references, CLI commands, and terminology throughout the document.
Security assessment
The changes are purely terminological updates to align with branding standards. There is no evidence of addressing security vulnerabilities, weaknesses, or incidents. Existing security-related features like price protection and performance protection are mentioned but not modified in functionality.
