### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

I have an application which uses SQS.
It works in production.
It has acceptance tests which were passing with localstack until very recently.

Now I see:

```
An error occurred (InvalidParameterValue) when calling the SendMessage operation: Value 0 for parameter DelaySeconds is invalid. Reason: The request include parameter that is not valid for this queue type.
```

Yes, delay `0` is being passed in to `send_message` but this used to work in both localstack and AWS.

https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/sqs.html#SQS.Client.send_message

> DelaySeconds (integer) --
The length of time, in seconds, for which to delay a specific message. Valid values: 0 to 900. 

### Expected Behavior

DelaySeconds 0 is a valid value.

sqs send_message works when explicitly setting delay 0.

### 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)

1. Create a SQS FIFO queue.
2. Try to `send_message`, specifying `DelaySeconds=0`

### Environment

```markdown
- OS: macos
- LocalStack: latest
```


### Anything else?

I notice on a recent issue that @thrau said he recently changed how SQS attribute values are validated.
return self.message["MessageId"] == other.message["MessageId"]
    def __hash__(self):
        return self.message["MessageId"].__hash__()

        self._assert_queue_name(name)
