AWS vpn documentation change
Summary
Renamed and restructured documentation from transit gateway VPN attachment to general VPN connection creation. Added support for Cloud WAN global networks, VPN Concentrators, and unattached VPN connections. Removed CLI-specific instructions and IPv6 viewing details.
Security assessment
The changes focus on expanding supported VPN connection types (Cloud WAN, Concentrators) and restructuring content. No security vulnerabilities or mitigations are mentioned. The addition of certificate ARN references maintains existing security practices but doesn't introduce new security documentation.
