Thanks for your contribution!

But this is not a valid patch for Wine.

You need to put your changes in a current Wine git repo folder,  and use `git add po/ko.po` and `git commit -m "po: Update `Korean translations."` to save your changes.

You may also need to use `git format-patch` to generate a patch.

Also you should sign your patch. You can use `git config format.signOff true` for enabling 'signoff' in your Wine git repo.
