TYPO3 Core

Hello,

I'm neither a typo3 nor php developer, and I don't know if this is the right place? Do you have a repo where I can create a proper pull request somewhere?
Anyway one of my customers has a typo3 v11.5.5 installed and has hundred's instances of an error in their log-files nagging about a problem with $menu on line 420 of typo3/sysext/frontend/Classes/DataProcessing/LanguageMenuProcessor.php - I fixed it with a if(is_iterable($menu)) clause. Again, I'm not a php developer, there might be a proper way to do this, but it fixes the problem. My customer and I would be very happy to not have to manually patch this after every typo3 update...
So please include it (or a better fix) in the next release. Thank you!

            if(is_iterable($menu)) {
                foreach ($menu as $key => $language) {
                    $processedMenu[$key] = $language;
                }
            }
