Summary

Modified prerequisites to emphasize secure access setup and removed GPG key expiration warning for Linux installer verification.

Security assessment

The removal of the GPG key expiration warning eliminates a security notice about future verification requirements, potentially impacting users' ability to validate installers after 2025. However, the change also adds security documentation by updating prerequisite language from 'administrative IAM user' to 'secure access to AWS', promoting better security practices.
