Outdated F-Droid app description

The link in your app's description in [F-Droid's app description is outdated](https://f-droid.org/en/packages/com.app.openlib/). I think the working one (not sure if genuine) is this one: https://annas-archive.cc/

Please update the app's description.

Start with the F-Droid app description linked in the issue and locate the repository's source for that description. Confirm the correct Anna’s Archive URL, update the outdated link, and verify that the published description points to the working destination.
