"Edit document"goes to 404 error page

I think there is a 🐛 (bug) with "edit document":
https://github.com/docsifyjs/docsify/blob/master/docs/index.html#L65

If we are on default language, no 🐛 but, in other language, we'll have 404 error.
Check it out:

1. 🇺🇸 : https://docsify.js.org/#/quickstart click on: "Edit document". Result: OK !
2. 🇩🇪 : https://docsify.js.org/#/de-de/quickstart click on: "Edit document". Result: 404 error page! 👎
3. 🇪🇸 : https://docsify.js.org/#/es/quickstart click on: "Edit document". Result: 404 error page! 👎

@QingWei-Li now if you click on "Edit document" here: https://docsify.js.org/#/quickstart you have 404 error. 😢

But, you fixed the "edit document" in other languages 👍
