fixed vite/ssr error on build

see sveltejs/kit#928

```
Named export 'faAsterisk' not found. The requested module '@fortawesome/free-solid-svg-icons' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from '@fortawesome/free-solid-svg-icons';
const { faArrowLeft, faArrowRight, faAsterisk, faArrowRotateLeft, faFolderPlus, faEllipsis } = pkg;
```
