AWS marketplace: Add regional and global endpoint formats for Discovery API
Summary
Adds the regional endpoint format (discovery-marketplace.region.api.aws) and documents the global endpoint (discovery-marketplace.global.api.aws), noting that global endpoint requests must be signed with SigV4a and that pagination tokens aren't portable across Regions.
Security assessment
This is endpoint reference documentation that briefly restates the SigV4a authentication requirement for the global endpoint. It is security-adjacent (authentication) but contains no vulnerability-specific or incident-specific content.
Evidence
Requests to the global endpoint must be signed with AWS Signature Version 4A (SigV4a), and pagination tokens aren't portable across Regions.
