fix: Correct IAM role ARN format with double colon

- Fix IAM role ARN format from 'arn:aws:iam:ACCOUNT_ID:role/ROLE_NAME'
- to 'arn:aws:iam::ACCOUNT_ID:role/ROLE_NAME' (double colon)
- This was causing 'Request ARN is invalid' error in GitHub Actions
- Update PowerShell script to generate correct ARN format
