[Enhancement]: aws_codeartifact_domain: add s3 bucket ARN attribute

[Michagogo]

Description

The DescribeDomain API returns a value, s3BucketArn, which contains (surprise!) the ARN of the S3 bucket that is used to store package assets for that domain. It would be useful to be able to reference that value in order to allow access to it in various policies (IAM, VPCE, etc.), but right now as far as I can tell it’s not exposed as an attribute of the resource.

Affected Resource(s) and/or Data Source(s)

aws_codeartifact_domain

Potential Terraform Configuration

resource "random_pet" "domain" {}

resource "aws_codeartifact_domain" "example" {
  domain = random_pet.domain.id
}

locals {
  package_bucket = aws_codeartifact_domain.example.s3_bucket_arn
}

Note that this seems slightly less important as it did at the time, as it turns out that (according to a response from the service team, via Support, after I observed differing behavior) the CodeArtifact documentation is somewhat outdated and, despite saying that access to the S3 bucket is necessary in order to fetch the actual artifacts, when downloading packages (at least, Python packages from PyPI - I didn’t test other types.) the packages are downloaded via the CodeArtifact VPC endpoint with no direct access to S3.
That said:
• I don’t know whether this is the case with other package types, and it’s possible that in some scenarios it is necessary to grant access to the bucket
• There may be other use cases for having easy access to the information about the underlying bucket that aren’t coming to mind immediately
• The attribute is returned by the Describe API

So it’s still probably a good idea to add the attribute to the resource and data source.
