fix(verify-flatpak): sync overlay with vid's desktopApp rename

Upstream manifest at vidplace7/org.meshtastic.desktop now references
desktopApp/ instead of the old desktop/ module path. Our overlay was
stale and failed with `sed: can't read desktop/build.gradle.kts: No
such file or directory` partway into the build phase.
