### Is there an existing issue for this?

### Current Behavior

When re-subscribing an SQS queue to an SNS topic with the attribute "RawMessageDelivery=true", localstack throws an error.
It's occuring both on my AWS Java Client and with CLI awslocal
it's working well without this attribute


### Expected Behavior

Since the queue is subscribed with the attribute "RawMessageDelivery=true" to the topic already, it should be a no-op and simply return the same subscription arn.



### 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

#### Client commands (e.g., AWS SDK code snippet, or sequence of "awslocal" commands)

```
awslocal sns create-topic --name localstack-topic
awslocal sqs create-queue --queue-name localstack-queue

awslocal sns subscribe   --topic-arn arn:aws:sns:eu-central-1:000000000000:localstack-topic    --protocol sqs    --notification-endpoint arn:aws:sqs:eu-central-1:000000000000:localstack-queue    --return-subscription-arn  --attributes RawMessageDelivery=True

awslocal sns subscribe   --topic-arn arn:aws:sns:eu-central-1:000000000000:localstack-topic    --protocol sqs    --notification-endpoint arn:aws:sqs:eu-central-1:000000000000:localstack-queue    --return-subscription-arn  --attributes RawMessageDelivery=True
```

### Environment

```markdown
aws-cli/1.22.34 Python/3.10.12 Linux/6.2.0-32-generic botocore/1.31.47
```


### Anything else?

subscription created with "RawMessageDelivery=true"

but if the subscription is created without attributes it's working well
