Make it possible to run under Wayland

[illode]

Fixes #1527 by adding the chromium flags needed to run under Wayland.

Flags

Since chromium parses the flags regardless of chainner, preventing the arg parser from throwing an error is enough to make the flags work. Technically, this can be done in v0.19.4 already using chainner open '' --ozone-platform-hint=auto, but that's cumbersome and not obvious.

Ideally --ozone-platform-hint should be enabled by default, but I couldn't find a way to pass it to electron outside of the CLI. The arg parsing would probably have to be done in a wrapper that calls the real chainner binary for this to work.

desktopName package.json field

On Wayland, if the .desktop file name doesn't match the app_id, the compositor won't be able to find .desktop file and thus can't find the icon. With the desktopName field unset, electron falls back to chaiNNer.desktop as the app_id, but the Linux makers all package the .desktop file as chainner.desktop. Since they don't match, the icon is missing. The desktopName field can be used to manually specify the app_id so everything works as expected.

I'll trust you that this works. Thanks!
