Bitwarden's icon on F-droid is blurry (not sharp)

[aha999]

On F-droid, the icon of Bitwarden is of low quality or blurry, while icons of other apps are sharp:

This is because the asset used for the app icon doesn't have alternate sizes available depending on the screen density. I had the same issue in another app and fixed it by generating all five alternates.
