AppImage fails to start / missing libfuse.so.2

[turbotimon]

How to reproduce / behaviour on my system:

• System is: Linux kub 7.0.0-27-generic Speculative decoding article skeleton #27-Ubuntu (Kubuntu)
• Download the AppImage from: https://lmstudio.ai/download/latest/linux/x64
• Double click AppImage, nothing happens
• Starting from console: ./LM-Studio-0.4.21-2-x64.AppImage reveals dlopen(): error loading libfuse.so.2
• Installing the missing lib solves the problem

Improvement suggestions:

• Mention the lib(s) in system requirements
• Check dependencies that are not bundled in AppImage on startup and provide a GUI message
