Fix implicitly nullable parameter warning in PHP 8.4+

[SagePtr]

Fix deprecation warnings in PHP 8.4 and PHP 8.5:

PHP Deprecated:  JsPhpize\Nodes\Dyiade::__construct(): Implicitly marking parameter $before as nullable is deprecated, the explicit nullable type must be used instead in vendor/js-phpize/js-phpize/src/JsPhpize/Nodes/Dyiade.php on line 29
PHP Deprecated:  JsPhpize\Nodes\Dyiade::__construct(): Implicitly marking parameter $after as nullable is deprecated, the explicit nullable type must be used instead in vendor/js-phpize/js-phpize/src/JsPhpize/Nodes/Dyiade.php on line 29

UPD: this will break PHP 7.0 compatibility (which support ended 6 years ago)

Hello, thanks for raising. ?array is not compatible with PHP 7.0, however I checked, and we don't need to keep them nullable. I'll switch those to pure array parameters in #42 which will be compatible with all versions from 7.0 to 8.5.

Fixed in version 2.9.2
