Missing dependency

Description:

Without the archlinux-appstream-data package, gnome-software cant't show properly the app details page: the Open/trash boxes disappear after a (few?) frame(s) and the "Flathub v" button doesn't suggest any arch package. However, this bug is fixed when installing the archlinux-appstream-data package.

Additional info:

• package version(s): 47.4-1
• link to upstream bug report, if any: https://gitlab.gnome.org/GNOME/gnome-software/-/issues/2762

Steps to reproduce:

1. Ensure that you don't have the archlinux-appstream-data package
2. Go in the gnome-software app, in the "Installed" window
3. Go in the app detail page of any arch package
