     * NumberFormatter::GROUPING_USED value when using PHP's NumberFormatter
     * class. Its documentation is non-existent, but it appears that if you set
     * this to true, numbers will be grouped with a comma or period (depending
     * on your locale): 12345.123 would display as 12,345.123.

It seems like $grouping defined by parameter $grouping on line 43 can also be of type string; however, Symfony\Component\Form\Extension\Core\DataTransformer\MoneyToLocalizedStringTransformer::__construct() does only seem to accept boolean|null, maybe add an additional type check?
