Publish Fincept terminal as a flatpak on flathub

I have moved most of if not all of my Linux "app" usage to getting them from flathub as flatpak so I can keep my base system stable and updated without braking any of the apps I use.

Therefore it would be great if Fincept terminal was available on flathub.

Having it on flathub would also have the benefit of given every Linux user, from Ubuntu to Gentoo, a consistent way to I install Fincept terminal regardless of what Linux distribution they are on
