AWS sap documentation change
Summary
Fixed broken link in encryption documentation, updated formatting (hyphens, spacing), and minor text adjustments. Added valid URL for S3 default encryption guide.
Security assessment
The change fixes a broken link in the encryption section, ensuring users can properly implement server-side encryption with KMS or S3-managed keys. While encryption is a security feature, the change itself does not address a specific vulnerability but improves documentation accuracy for existing security controls.
