auto-cpufreq-gtk Fails to Start Due to Missing Icon File

Describe the bug

When attempting to launch auto-cpufreq-gtk, the application crashes with a gi.repository.GLib.GError. The error indicates that the application is trying to open an icon file (auto-cpufreq.png) from a path that does not exist in the Nix store. As a result, the GTK interface fails to initialize. Error Traceback:

Steps To Reproduce

Steps to reproduce the behavior:

Install auto-cpufreq using Nix.
Attempt to start the GTK interface by running auto-cpufreq-gtk in the terminal.
