Summary

Updated IAM role ARN pattern to include additional AWS partitions (aws-cn, aws-us-gov, aws-iso variants).

Security assessment

This change expands the validation pattern for IAM role ARNs to include additional AWS partitions but does not address any security vulnerability or weakness. It's a documentation update to reflect broader AWS partition support.
