Notifications: Also try X-SnapInstanceName for desktop file resolution
We already do it for X-Flatpak-RenamedFrom.
We also check the BAMF_DESKTOP_FILE_HINT
in the environment but it seems
Chromium-based apps mess with their environment in an way that the environment
in /proc
becomes unreliable.
Needs frameworks/kservice!123 (merged) for the service definition.
My snap Slack notifications show up properly now.
