Fix linux appimage task

[COD3HUNT3R]

Currently appimage builds are broken as per #4641

This fixes appimage builds.

Summary by CodeRabbit

• Bug Fixes

  • AppImage now uses the correct app-specific icon, improving how the app appears in desktop environments, launchers, and file managers and avoiding icon conflicts across builds.

• Chores

  • Build process updated to dynamically name the app icon from the application name, ensuring consistent branding for generated AppImages.

Walkthrough

Updated the Linux Taskfile to make the AppImage icon filename dynamic by using {{.APP_NAME}}. The create:appimage task now copies ../../appicon.png to {{.APP_NAME}}.png and sets ICON to {{.APP_NAME}}.png instead of a fixed ../../appicon.png.

Changes

Poem

I nibble bytes with whiskers bright,
Renamed the icon to shine just right.
From static PNG to APP_NAME's glow,
AppImage now wears the name we know.
Hop, commit, and off we go! 🐇✨
