ecs s3 environment's arn path is incorrect if partition is aws-gov

[ivyxjc]

What is the problem?

We use aws-gov cloud. And I try to bind s3 environment to ecs. The generated cloud formation of the config is still
arn:aws:s3:::.....

following is the sample code

const bucket = s3.Bucket.fromBucketArn(this, `${props.resourcePrefix}-Bucket`, `arn:aws-us-gov:s3:::${props.configBucket}`)
....

const container = taskDefinition.addContainer(`${props.resourcePrefix}-Web`, {
      containerName: `${props.resourcePrefix}-Web`,
      image: ecs.ContainerImage.fromEcrRepository(repo, props.tag),
      memoryReservationMiB: props.containerMemoryReservation,
      logging,
      environmentFiles: [EnvironmentFile.fromBucket(bucket, `${props.configPath}`)]
    });

I review the source code of aws-cdk, I think the following code is the root cause. The arn may should use bucket's arn otherwise hard code arn:aws:s3:::....

aws-cdk/packages/@aws-cdk/aws-ecs/lib/container-definition.ts

Line 771 in 4937cd0

value: `arn:aws:s3:::${s3Location.bucketName}/${s3Location.objectKey}`,
