Warnings when running Restler with PHP 8.2 Context

We have recently updated our System to TYPO3 12LTS with PHP 8.2.

When calling now an url in the Frontend, the following warning is now generated:

`Core: Error handler (FE): PHP Warning: Uninitialized string offset -1 in /var/www/html/vendor/aoe/restler/Classes/System/Restler/RestlerExtended.php line 127`
