gs-prefs-dialog: Fix "Only Show Verified Developers" option title
requested to merge automerisnaranja/gnome-software:only-show-verified-developers-option-fix into main
The option title is currently "Only Verified Developers", but this phrase sounds awkward due to the lack of a verb. Fix that by renaming the option to "Only Show Verified Developers".
