Update librivox-indonesia.py

In the ```datasets``` library version 3.0.0, I encountered the error ```TypeError: DownloadConfig.__init__() got an unexpected keyword argument 'ignore_url_params'``` when using ```load_dataset()```. I believe this line is unnecessary: ```dl_manager.download_config.ignore_url_params = True```. I tried it locally, and it worked fine when I commented out that line.
