Provide option to install via snap and/or flatpak packages

[erlisdhima]

Hi,

It would be great if there was an option to install terminalizer through a flatpak, or using a snap package.

I was checking if this was possible and I found this for flatpak: https://www.npmjs.com/package/flatpak-bundler
Not sure if its still being maintained or if it works, but just wanted to mention in case its useful.

Thanks!
