AWS vpc documentation change
Summary
Updated documentation to replace 'Amazon VPC Transit Gateways' with 'AWS Transit Gateway' throughout the file, including title changes and link references. Minor grammatical correction from 'their destination IP addresses' to 'the destination IP addresses'.
Security assessment
Changes are purely branding/naming convention updates and grammatical corrections. No security-related content was added, removed, or modified. The updates maintain existing security context without introducing new security implications.
