ARN Parser Util Package's Build Method Generates Invalid ARN for S3 Resources #7621
Description
Checkboxes for prior research
- I've gone through Developer Guide and API reference
- I've checked AWS Forums and StackOverflow.
- I've searched for previous similar issues and didn't find any solution.
Describe the bug
It seems that S3 resource ARNs are formatted differently from those of most other AWS resources, as account ID and region are omitted in S3 resource ARNs.
However, the current build method in the ARN parser util package seems to not distinguish S3 resources from other resources when generating ARNs.

Reproduction Steps
import { build, parse } from "@aws-sdk/util-arn-parser";
function generateArn() {
return build({
partition: "aws",
accountId: "123456789012",
region: "us-east-1",
service: "s3",
resource: "a-bucket",
});
}
console.log(generateArn()); // arn:aws:s3:us-east-1:123456789012:a-bucket - I believe this is incorrect as the region and account ID should be omitted, like arn:aws:s3:::a-bucket .
Observed Behavior
For S3 resources, the build method generates incorrect ARNs that include region and account ID.
Expected Behavior
For S3 resources, the build method should generate ARNs that do not include region and account ID.
Possible Solution
Omit region and account ID in if service is s3 in the relevant code.
