[Feature] Add framalibre to the list of french resources in "what's next" page

We could add [framalibre](https://framalibre.org/) to the list of resources we mention in the "what's next" page in french : https://reports.exodus-privacy.eu.org/fr/info/next/

I think that would make sense in the part named "Découvrir des alternatives"

Open the French “what’s next” page at https://reports.exodus-privacy.eu.org/fr/info/next/ and find the section “Découvrir des alternatives.” Add Framalibre (https://framalibre.org/) to that resource list, then verify the link and French page rendering.
