### Current Behavior

When performing a multipart upload, sending part number 10000, because [this check](https://github.com/localstack/localstack/blob/d23f0717cc66c0cc8a61b6b85e7531a6f4a03f96/localstack/services/s3/provider.py#L792C88-L792C88) in s3/provider.py is wrong.

### Expected Behavior

Part number 10000 is accepted

### 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)

I'm using AWS .NET SDK:

        using var inputStream = new MemoryStream(buffer, 0, readBytes, false);

        var uploadRequest = new UploadPartRequest
        {
            BucketName = bucketName,
            InputStream = inputStream,
            Key = key,
            PartNumber = partNumber,
            PartSize = readBytes,
            UploadId = uploadId,
        };

        await _client.UploadPartAsync(uploadRequest);


### Environment

```markdown
- OS: Ubuntu 22.04
- LocalStack: 2.2
```


### Anything else?

As referenced above, the bug is in [this line](https://github.com/localstack/localstack/blob/d23f0717cc66c0cc8a61b6b85e7531a6f4a03f96/localstack/services/s3/provider.py#L792C88-L792C88). It should read
