• Guess bin/shortcuts fields could be added as well.
• Please update to the latest version.

The installer automatically creates the shortcut, so including the shortcut property would create two of them, which I find unnecessary. I have added the following section to the manifest explaining why the shortcut property isn't included:

"##": [
        [
            "Shortcut section omitted as it is automatically created by the installer.",
            "bin/bin/chat.exe",
            "GPT4All"
        ]
    ],

The comment explaining why the shortcut section was omitted has been modified as follows to resolve the workflow syntax checker issue (comments can not contain arrays).

"##": "Shortcut section omitted as it is automatically created by the installer.",

@aliesbelik, could you please take a look at this?
