Would it be possible to add `js` and `css` extensions to the [`theme authorized extensions`](https://discourse.theme-creator.io/admin/site_settings/category/files?filter=theme_authorized_extensions) setting?
I’m trying to install my [Notification Banners](https://meta.discourse.org/t/notification-banners/325279) theme-component to create an online demo, and that is unfortunately a requirement:

> 1. Follow the official instructions to add this theme-component to your theme:

> 2. Change [`theme authorized extensions`](https://meta.discourse.org/admin/site_settings/category/files?filter=theme%20authorized%20extensions) setting to include `css` and `js` file extensions.

Hi Osman, I had a look and `js` is already allowed and i just added `css`.
