- Add Spanish and Dutch as languages
- Replace "GrassCutter" with "GrassCutter"
- Fix minor problem with package.json
- Fix some potential terminology problems
1 :I think "GrassClipper" is a proper noun,its inappropriate to translate it literally.
2:"Play(游玩)" is not "launch(启动)".
3:“Genshin Impact Game(原神)” is not translated.
4:"killswitchSubtitle" is completely wrong.
5:“set” here is preferably translated as "选择(select)"
6: Change some expressions of "folderNotSet" to let it looks clearer
