Hello,
On the French Kubernetes website page : https://kubernetes.io/fr/docs/tutorials/kubernetes-basics/ some strings related to the outdated content notice are still displayed in English.
After checking the template, I found the following code
However, the keys outdated_content_title and outdated_content_message do not exist in i18n/fr/fr.toml.
Because of that, the text remains in English on the French version of the site.
Proposed fix
Add the missing keys to i18n/fr/fr.toml with appropriate French translations.
