AWS AWSCloudFormation documentation change

File: AWSCloudFormation/latest/UserGuide/peer-with-vpc-in-another-account.md

Summary

Updated resource reference links and added PDF reference. Content about VPC peering configuration remains functionally unchanged.

Security assessment

Changes are limited to documentation links and formatting. While VPC peering has security implications, the modifications don't introduce new security guidance or address specific vulnerabilities. The security context of cross-account peering was already covered in original documentation.
