### 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.
with self.mutex:
            if self.thread:
                return
            self.scheduler = Scheduler()
            self.scheduler.schedule(self.do_update_all_queues, period=1)
            def _run(*_args):
                self.scheduler.run()
            self.thread = start_thread(_run)
    def stop(self):
        with self.mutex:
            if self.scheduler:
                self.scheduler.close()
            if self.thread:
                self.thread.stop()
            self.thread = None

    for attribute_name in message_attributes:
        if len(attribute_name) >= 256:
            raise InvalidParameterValue(
                "Message (user) attribute names must be shorter than 256 Bytes"
            )
        if not re.match(ATTR_NAME_CHAR_REGEX, attribute_name.lower()):
            raise InvalidParameterValue(
                "Message (user) attributes name can only contain upper and lower score characters, digits, periods, "
                "hyphens and underscores. "
            )
