Kindly PR to the dev branch

Thanks so much for taking the time to submit this fix!

I actually completely forgot that I recently migrated the App Launcher to use Quickshell's native DesktopEntries module over on the dev branch. Because of that architectural change, list_apps.py is now dead code and no longer used by the shell at all (plus, the native module automatically handles XDG_DATA_DIRS out of the box).

I'm going to close this PR and have already deleted the obsolete Python script from the codebase entirely so it doesn't cause any more confusion. Thanks again for the contribution!
