### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

When passed to SQS, keys of the messages attributes on SNS are renamed from StringValue to Value and DataType to Type.

### Expected Behavior

The keys should not be renamed

### How are you starting LocalStack?

With a docker-compose file

### Steps To Reproduce

#### How are you starting localstack (e.g., `bin/localstack` command, arguments, or `docker-compose.yml`)

    docker run localstack/localstack

#### Flow
 - Create a SQS Queue
 - Create a SNS Topic
 - Configure a Subscription of the new Topic that sends to the SQS queue (specify a raw delivery at true)
 - Publish a message to SNS Topic with attribute { DataType: "string", StringValue: "anything"}
 - Attributes are no more StringValue but just value. 

(can't provide more, I have issues with my awslocal, I got this issue with the PHP client initially)

### Environment

```markdown
- OS: Docker Desktop for mac
- LocalStack: 1.4
```


### Anything else?

The AWS SNS official documentation : https://docs.aws.amazon.com/sns/latest/api/API_MessageAttributeValue.html
