### Steps to reproduce

Just logout of any accounts you have and see the welcome screen, as long as your system language is French.

### Expected behaviour

The French translation on the Android client welcome screen is extremely confusing:

"Se connecter avec un fournisseur" means "Log in with a provider," yet clicking on it leads to the sign-up with a provider page.

"Hébergez votre propre serveur" means "Host your own server", and clicking on it leads to the self-hosting documentation.

This is highly confusing! Whether a user is with a provider or self-hosting, the actual login is done via the "Se connecter" option. The other two options should have been translated as "S'inscrire avec un fournisseur" ("Sign up with a provider") and "Comment s'auto-héberger ?" ("How to self-host?").

I spent about 30 minutes combing through the documentation, confused by this wording, and I’m probably not the only one.
