fix: PHP Deprecated: Creation of dynamic property Valet\Diagnose::$progressBar error.

The creation of a dynamic property without being defined first is deprecated in PHP 8.2. See https://php.watch/versions/8.2/dynamic-properties-deprecated for more info.

`progressBar` property is being dynamically created in `Diagnose::beforeRun` method. To fix the deprecation error, we just need to declare the property in the class first.
