AWS Terraform fixes for license and update output of web address. (#47349)

* Two small fixes

1. Changes SSM tier to Advance to support new self hosted keys that are 4k+ in size.
2. Updates output of web address to use fqdn when ACM is disabled.

* Use "Intelligent-Tiering" to allow Terraform to pick the necessary Tier.
