fix: Add context tags to the IAM resources

[natemccurdy]

what

Add tags = module.this.tags to each of the IAM resources so that they use the tags determined by the null/label context or the tags input.

why

Prior to this, the aws_iam_role and the aws_iam_policy created by this module did not include any of the tags passed via tags or via context.

 ## Modules

README.md is outdated. Please run the following commands locally and push the file:
  make init
  make readme

That shouldn't happen because make readme should use a specific version of tf-docs and be consistent... Do you have pre-commit installed globally maybe? If you can, check that out and if worst comes to worst, I'd change the README.yaml / README.md manually to address that.

Do you have pre-commit installed globally maybe?

I do not have pre-commit installed globally.

I've fixed the docs manually as per your suggestion.

@Gowiem Great, tests are passing. What are the next steps now? Looks like we need another approval?

[Gowiem]

@natemccurdy Yeah -- Need an org owner to approve. I've requested someone to do that in our contributor channel. Will follow up!
