Install or enable PHP's intl extension. - Root composer.json requires typo3/cms-lowlevel ^12.0 -> satisfiable by typo3/cms-lowlevel[v12.0.0, ..., v12.4.16]. To enable extensions, verify that they are enabled in your .ini files: - /usr/local/etc/php/php.ini - /usr/local/etc/php/conf.d/docker-php-ext-opcache.ini - /usr/local/etc/php/conf.d/docker-php-ext-sodium.ini You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode. Alternatively, you can run Composer with `--ignore-platform-req=ext-intl` to temporarily ignore these required extensions.
