Document required packages for AppImage on barebones Ubuntu server 22.04

[lrettig]

Environment

• Smapp version: 1.3.10
• Node version: 1.3.10
• OS: Ubuntu server Ubuntu 22.04.4 LTS

Describe the bug

I get a series of missing shared library errors when trying to run the AppImage out of the box:

$ ./Spacemesh-1.3.10.AppImage
dlopen(): error loading libfuse.so.2
AppImages require FUSE to run.
You might still be able to extract the contents of this AppImage if you run it with the --appimage-extract option.
See https://github.com/AppImage/AppImageKit/wiki/FUSE for more information

Steps to reproduce

Run the AppImage on a fresh Ubuntu server install

Expected behavior

The AppImage should work out of the box, or at least the list of required packages should be clearly documented

Actual behavior

See above

How to fix

I worked around it by apt install ing the following packages: libfuse2 libnss3 libatk1.0-0 libatk-bridge2.0-0 libcups2 libgtk-3-0 libasound2
