Tray for Linux not implemented

[lukaskretzschmer]

I was checking src/main/tray.ts and I noticed that no tray options are being shown for Linux, also there's a popout that shows null and there is currently an issue which I explained on https://github.com/internxt/drive-desktop/issues/118 so maybe this is causing it.

Hi, just commenting that the implementation for the tray doesn't seem to be complete as it doesn't work for me also (Gnome 42.4).
