I am trying to display a date in French using Twig filter format_datetime. For instance, this code:
'2024-05-05 23:39:12'|format_datetime(locale='fr',pattern="EEEE dd MMMM YYYY") should display Dimanche 05 Mai 2024 but its displaying Sunday 05 May 2024 instead.
My setup :

• Symfony 6.4
• “twig/extra-bundle”: “^3.9”
• “twig/intl-extra”: “^3.9”
• In docker, I am using: php:8.3-fpm-alpine, docker-php-ext-configure intl, docker-php-ext-install intl
• default locale is set to ‘fr’

I don’t know what I am missing here.
