Add zh_TW.md

This is the Traditional Chinese translation (zh-TW) for the Help page.

@reiscigit How do you think, would it be helpful for those, who use Chinese Simplified? If it could be useful, could you please rename the file to zh.md? If not, could you please right-click Dark Reader icon, select "Inspect Popup", and run chrome.i18n.getUILanguage() in Console? This will give a proper file name. Most likely it will be zh-TW, without the underscore.

Could you please also share result of navigator.languages?

The reason for this confusion is that Chrome extensions use locale files names with underscores. I've just renamed the sources to use dashes.

Hi, @alexanderby
Sorry I misspelled the filename. It is better to separate the Simplified and Traditional Chinese. I should add the zh-CN.md for the Help page soon.

Great, thanks, I will publish it soon.
