NewerConcurrentVersions in LifecycleRuleNoncurrentVersionExpiration is ignored

[BreakingBread0]

Describe the bug

When setting a lifecycle configuration with noncurrent version expiry, NewerConcurrentVersions seems to not be serialized into the request (see https://github.com/aws/aws-sdk-net/blob/main/sdk/src/Services/S3/Custom/Model/Internal/MarshallTransformations/PutLifecycleConfigurationRequestMarshaller.cs#L124)

This doesnt appear to be right, especially since there is no documentation describing this behaviour. Having a quick look around, the PutBucketLifecycleConfigurationRequestMarshaller for S3Control seems to do serialize it (https://github.com/aws/aws-sdk-net/blob/main/sdk/src/Services/S3Control/Generated/Model/Internal/MarshallTransformations/PutBucketLifecycleConfigurationRequestMarshaller.cs#L172)

Expected Behavior

NewerNoncurrentVersions being written into the request.

Current Behavior

The NewerNoncurrentVersions is ignored during serialization.

Reproduction Steps

This is my current code:

PutLifecycleConfigurationRequest request = new()
{
    BucketName = bucketName,
    Configuration = new()
    {
        Rules = new()
        {
            new Amazon.S3.Model.LifecycleRule() {
                NoncurrentVersionExpiration = new LifecycleRuleNoncurrentVersionExpiration()
                {
                    NewerNoncurrentVersions = keepItems,
                    //NoncurrentDays = keepDays,
                },
                AbortIncompleteMultipartUpload = new LifecycleRuleAbortIncompleteMultipartUpload()
                {
                    DaysAfterInitiation = 7
                },
                Expiration = new LifecycleRuleExpiration()
                {
                    //Am object which only has deletion markers
                    ExpiredObjectDeleteMarker = true,
                },
                Id = lifecycleConfigName,
                Status = LifecycleRuleStatus.Enabled,
                Filter = new()
            }
        }
    }
};
