Executing Live AppImage requires workaround on Ubuntu 22.04LTS

[vasarhelyi]

Ubuntu 22.04 LTS comes with fuse3 that does not support AppImage execution by default, and if you install the recommended older fuse it removes many core packages (e.g. related to desktop, see e.g. https://bugs.launchpad.net/ubuntu/+source/fuse/+bug/1978310). A working workaround currently is to run the Appimage as

something.appimage --appimage-extract-and-run

Apparently this should be fixed in the most recent version of electron-builder. See electron-userland/electron-builder#6678 and electron-userland/electron-builder#8351 . electron-builder@25.0.3 or later should be okay. Needs testing.
