[FEATURE] Release the application with Flatpak on Flathub

[yookoala]

Problem

The Linux package provided by OpenCut is now in deb, which is a Ubuntu/Debian ecosystem-specific format. It is a good thing that you provide a Linux package. It would be even better if a package format is provided for Linux regardless of distribution.

Solution

Flatpak is a cross-distribution, optionally sandboxed format for distributing Linux desktop application. It would be a more ideal format for Linux distribution. And Flathub is the main application for Flatpak package distribution.

It is a bit of work to modify pipeline to distribute as Flatpak package. But it would then allow other popular distributions (e.g. RHEL / Fedora, Arch Linux) to take advantage of this application.

Alternative

Alternatively, there is also snap, which is proposed and maintained by Canonical (the company behind Ubuntu). This is, in my mind, a less favourable format because the format requires install and running an additional background application (i.e. daemon) even if no snap application is running. Flatpak is, instead, only requires a set of application tool.

Anything else?

I am running my laptop on a Fedora environment. And there is no easy way to install OpenCut.
