The KiCad nightly is displayed twice in the menu in Gnome Shell

Description

The KiCad nightly is displayed twice in the menu in Gnome Shell.

This is because it creates duplicite *.desktop files.

sudo find . -name "*.desktop" | grep kicad | grep nightly

./usr/share/kicad-nightly/applications/org.kicad.eeschema-nightly.desktop
./usr/share/kicad-nightly/applications/org.kicad.gerbview-nightly.desktop
./usr/share/kicad-nightly/applications/org.kicad.pcbnew-nightly.desktop
