fix: broken light theme (#136)

Symlinks are not sufficient for this.

```
Path traversal attempt detected: /usr/share/plasma/look-and-feel/dev.getaurora.aurora.desktop/contents/plasmoidsetupscripts/org.kde.plasma.folder.js is not inside /usr/share/plasma/look-and-feel/dev.getaurora.auroralight.desktop/
```

Technically we don't need ksplashrc to be setting this as the splash
screen is part of the theme but I feel like we should still set this in
this way as a fallback.
