[BUG] Switching app language to Norwegian Nynorsk breaks the app

[FID02]

Describe the bug
Thank you for adding Norwegian Nynorsk translations to this awesome app! Unfortunately, changing the app's language to Nynorsk makes the app display the full-screen message:

"Unable to load asset: "assets/translations/nn-NO.json".

This message is displayed upon every start of the app and there's no way to continue using the app. I have attached an app log further below.

To Reproduce
Steps to reproduce the behavior:

• Install Openreads 2.8.0
• Go to Settings > Language and select Nynorsk

Expected behavior
I'm assuming the app shouldn't break. 😄

Screenshots

Additional info(please complete the following information):

• App version: 2.8.0
• App source (F-Droid, Google Play, Github, AppStore):
• Manufacturer and model: Play Store
• OS and version: Android 15, January security patch level. Tested on Pixel 8 and 6a, but I'm assuming it occurs on every Android device.
