AWS r53recovery documentation change
Summary
Updated terminology from 'Auto Scaling groups' to 'Amazon EC2 Auto Scaling groups' and 'Auto Scaling' to 'Amazon EC2 Auto Scaling' throughout the document. Adjusted links and made minor text updates.
Security assessment
The changes are purely branding/naming updates with no security context. No vulnerabilities, security features, or security implications are mentioned or modified in the diff.
