Consider removing Terraform `moved` blocks once they are no longer needed

# 💡 Summary #

@mcdonnnj suggested removing the Terraform `moved` blocks introduced in #355.

## Motivation and context ##

I personally think the `moved` blocks can be left in, but you can enjoy my back-and-forth with @mcdonnnj [here](https://github.com/cisagov/skeleton-packer/pull/355#pullrequestreview-2223646409).

Start by reviewing PR #355 and the linked review discussion to understand why the Terraform `moved` blocks were introduced. Locate those blocks in the repository and determine whether their state-migration purpose is still needed; done means reaching a clear decision and removing them only if the project agrees they are no longer required.
