// This operation is not supported by directory buckets. Returns the website
// configuration for a bucket. To host website on Amazon S3, you can configure a
// bucket as website by adding a website configuration. For more information about
// hosting websites, see Hosting Websites on Amazon S3 (https://docs.aws.amazon.com/AmazonS3/latest/dev/WebsiteHosting.html)
// . This GET action requires the S3:GetBucketWebsite permission. By default, only
// the bucket owner can read the bucket website configuration. However, bucket
// owners can allow other users to read the website configuration by writing a
// bucket policy granting them the S3:GetBucketWebsite permission. The following
// operations are related to GetBucketWebsite :
//   - DeleteBucketWebsite (https://docs.aws.amazon.com/AmazonS3/latest/API/API_DeleteBucketWebsite.html)
//   - PutBucketWebsite (https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutBucketWebsite.html)
