User Story

As an I expect to have a codebase that is compatible with the updated AWS Provider and Terraform Versions So that When running and test the code we don't have 71 warnings that

"Warning: Argument is deprecated"
Use the aws_s3_bucket_server_side_encryption_configuration resource instead
(and 71 more similar warnings elsewhere)

Value / Purpose

Keep code in a operational state.
