AWS prescriptive-guidance documentation change
Summary
Updated documentation links, fixed image paths, corrected URL formatting, and added explicit references to AWS DMS/SCT documentation. Removed redundant double slashes in URLs and improved punctuation consistency.
Security assessment
Changes are primarily cosmetic and structural (link corrections, image path updates, punctuation fixes). No security vulnerabilities, patches, or security-specific features are mentioned. The reference to 'security-sensitive' applications is unchanged from previous content.
