PHP 8.4 deprecated implicitly nullable parameters and registerMacros() method fails.

[eneadm]

PHP 8.4 has deprecated implicitly nullable parameters. In previous versions, writing array $transformers = null was valid, but now PHP requires an explicit nullable type declaration using ?.

Error:

PHP Deprecated:  {closure:Algolia\ScoutExtended\ScoutExtendedServiceProvider::registerMacros():128}(): Implicitly marking parameter $transformers as nullable is deprecated, the explicit nullable type must be used instead in /var/www/html/vendor/algolia/scout-extended/src/ScoutExtendedServiceProvider.php on line 128

Fix:

Algolia\ScoutExtended\ScoutExtendedServiceProvider:L126

\Illuminate\Database\Eloquent\Builder::macro('transform', function (array $array, ?array $transformers = null) {
    foreach ($transformers ?? UpdateJob::getTransformers() as $transformer) {
        $array = app($transformer)->transform($this->getModel(), $array);
    }

    return $array;
});

This should fix the issue and makes the package fully compatible with the latest php version. Let me know if I should make a PR for this change :-)
