Installer french translation yaml file is broken

[michaelthieulin]

PHP Version

8.3.4

Shopware Version

6.6.0.3

Expected behaviour

When we choose the locale French for the Installation wizard language parameter, we expect the installer pages displays correctly in French.

Actual behaviour

A Twig\Error\RuntimeError occurred and the installer is broken as the installer locale seems to be store somewhere.

How to reproduce

Install the production version of shopware.
Start the installer in a browser and switch Installation wizard language to French.
A Twig\Error\RuntimeError occurred with message :

An exception has been thrown during the rendering of a template ("The file "/var/www/vendor/shopware/core/Installer/Resources/translations/translations/messages.fr.yaml" does not contain valid YAML: Unexpected characters near "est produite lors de l'extraction des informations de la base de données.'" at line 73 (near "database-configuration_fetch_error: 'Une erreur s'est produite lors de l'extraction des informations de la base de données.'").").
