Missing script in documentation: examples/scripts/prepare_wmt_data.sh

Hi, while going through the documentation page Translation — OpenNMT-py documentation I wanted to check out the examples/scripts/prepare_wmt_data.sh script, but it links to a 404. Can anyone provide this script? (Add it to github / or update the documentation?). Thanks

Hello,

I may need to update the doc.

Let me know if something is wrong in this one.
