[php-src] Issue #10287: DateTimeZone::listIdentifiers returns a timezone Etc/GMT+0 which can not be used by DateTimeZone constructor

Issue: https://github.com/php/php-src/issues/10287 Author: fuzin ### Description The following code: ```php <?php $timezoneIdentifiers = \DateTimeZone::listIdentifiers(\DateTimeZone::ALL_WITH_BC); foreach($timezoneIdentifiers as $timezoneIdentifier) { (new \DateTimeZone($timezoneIdentifier)); } ``` Resulted in this output: ``` PHP Fatal error: Uncaught Exception: DateTimeZone::__construct(): Unknown or bad timezone (Etc/GMT+0) ``` But I expecte if DateTimeZone::getIdentifiers retuns a timezone it is also possible to use it in constructor. It is working fine in PHP 8.2.0. ### PHP Version PHP 8.2.1 ### Operating System php:8.2-fpm-alpine
