### 🐛 Bug Description

We are very happy with using NextChat as our OpenAI API Webinterface and we use it in English.
When we use it all of the CN and TW masks show up, which is confusing for our users because we are european and can't read it.
Currently we have to manually adjust [the source code](https://github.com/ChatGPTNextWeb/ChatGPT-Next-Web/blob/main/app/masks/build.ts), so the `tw` and `cn` masks are not included.

### 🚦 Expected Behavior

It would be great to have one of two options:
1. Define the types of masks to include in the `.env`-File
2. Enable/Disable the correct masks based on the language selected
