Pint not show Error message when pint.json is not a valid json file

[Claudio Eyzaguirre]

• Pint Version: 1.0.0
• PHP Version: 8.1.7

Description:

If you try to run Pint with an invalid pint.json file, Pint ignore your custom file and run using the default preset rules.

It would be great if Pint could show an error so the developer can fix the error.

Steps To Reproduce:

Add a pint.json with the following content (Note trailing comma in Line 5):

{
    "preset": "laravel",
    "rules": {
        "concat_space": {
            "spacing": "one",
        }
    }
}

Add this lines to some php file (e.g: AppServiceProvider):

$user = 'John';
$contact_space = 'Hi' . ' ' . $user;

Run Pint:

./vendor/bin/pint
