fix: remove the definition of AWS provider in the module

There is a weird error in the failed job here below. I have tested working by removing the aws provider definition in this success job here.

The reason is that the terraform in the aws-dedicated-org repo is required_version = "~> 1.3" , therefore it has such limitation.

Note: I did not observe this error in terraform v1.4 like these ones we set up as ordinary aws security repos that use this module. Maybe also because we did not use the count, for_each or depends_on?

A module intended to be called by one or more other modules must not contain any provider blocks. A module containing its own provider configurations is not compatible with the for_each, count, and depends_on arguments that were introduced in Terraform v0.13. For more information, see Legacy Shared Modules with Provider Configurations.
