zcode in a docker container!

Hello, I posted a week ago that i wanted to run zcode in a container, now I had the time to solve it. I had this old project that run opencode in a container, so thank you to glm and its flash little brother I added support to the features needed for zcode AppImage to run: a graphical ui support, fuse file system, xdg-open for the oauth flow to work, and xdg portal for the file picker to select projects.
The project is on github and works on my archlinux setup. I don't plan to support more architectures since i can't test them, but i hope it may serve as reference if anyone want to build on this.
Happy hacking!
