reopen pr#308

Description

Mirrors the BGP dynamic routing additions across both published specs (static/api.yaml and static/models.yaml) for the VPN network infrastructure schemas:

• VpnConnection — added bgpAsn, bgpPeeringAddress, adobeApipaAddress
• NetworkInfrastructure — added adobeAsn; documented multi-connection support (recommended max 20) and static/BGP mix in the connections description
• GatewayInfrastructure — addressSpace is no longer required (it's optional when a connection uses BGP dynamic routing; required only for static-routing connections)

Related Issue

N/A — documentation update tracking the network-infrastructure BGP feature.

Motivation and Context

The self-service-gateway now supports BGP dynamic routing for VPN network infrastructures. The public API reference did not describe the new fields (bgpAsn, bgpPeeringAddress, adobeApipaAddress, adobeAsn) or the relaxed addressSpace requirement, so integrators had no documented way to configure dynamic routing. This change brings the two published specs in line with the implementation. Field descriptions and constraints were verified against the cm-hub self-service-gateway source of truth (VpnInfrastructureRepresentation, NetworkInfrastructureService).

How Has This Been Tested?

• Both static/api.yaml and static/models.yaml parse cleanly as YAML.
• Each documented constraint cross-checked against cm-hub validation code (APIPA range 169.254.21.0–169.254.22.255, adobeAsn range 64512–65514/65521–65534, bgpAsn↔bgpPeeringAddress co-presence, MAX_VPN_CONNECTIONS = 20, conditional addressSpace requirement).
