AWS solutions documentation change
Summary
Updated documentation formatting, stability badge, reference links, parameter table structure, architecture diagram description, and GitHub section. Changed 'GitHub' to 'Github' and fixed internal links.
Security assessment
Changes are primarily formatting, branding (GitHub case), and documentation structure. No explicit security-related content added or modified. References to VPC and IAM roles are part of existing architecture descriptions but do not introduce new security guidance or address vulnerabilities.
