Add Flatpak/Flathub as a distribution channel for Linux

[bevsxyz]

在什么情况下你需要该特性？In what scenarios do you need this feature?

Currently, the available means to use Siyuan on Linux is with AppImage or from a tar file. As good as having options for Linux already, I think we could do one better by using a distribution channel supported by a popular package manager.

描述可能的最优解决方案 Describe the optimal solution

Flatpak is one of the best distro independent package management system for Graphical apps on Linux. Flathub is the official central repository where developers could submit their apps.

Siyuan already fulfills the technical requirement of a unique application ID. I think we are pretty safe on the legal requirements of license. However, it would be a good idea to check the requirements.

The app submission is straightforward and the instructions for it can be found here. I think it would be better if one of the developers took up control of this distribution.

We could check out the Flathub manifest for the Bitwarden client for a reference.
