request()->postData() not working for JSON requests

[patrickvuarnoz]

The postData() method only looks at $_POST which does not cover the data from a JSON request body:

public static function postData($item = null, $default = null)
{
    return \Leaf\Anchor::deepGet($_POST, $item) ?? $default;
}

Interestingly the get() method does. And rawData() also. This might be confusing for someone not sending form data to the server as it is not intuitive.
