include information about the start page alias

[fritzmg]

I have added a section explaining the mechanic with the index alias of the start page. It's a feature that has never been documented and many users still do not know about this.

Any comments on the wording?

Yes, it's perfect ;-)

[fritzmg]

ok :)

@lionel-m could you provide the French translation?

Hi, Sorry to answer only now...

could you provide the French translation?

Yes, all additions are translated in the three languages :)

using its alias and the globally defined suffix (e.g. http://www.example.org/home.html)

With "globally defined suffix" you mean .html? If that is the case, I would like to add that clarification.

No, the suffix could also be .htm or the like. That said, I would prefer the term "globally defined suffix" since it covers all possibilities that one might define in the system settings.

Ok it can change... I wanted to give an example to make this term more easily understood.

The French translation

### Page d'accueil

Lorsque le front office est ouvert avec une requête d'URL vide (par ex.
`http://www.example.org/`), Contao affichera la première page publiée dans
la racine du site internet respectif. Vous devez définir `index` comme alias
de cette page. C'est seulement alors que l'URL généré pour cette page sera
également une requête vide.

À partir de la version `3.5.18`, Contao redirigera automatiquement vers la page
d'accueil même si l'alias n'est pas défini comme `index`. L'URL comprend alors
l'alias et le suffixe défini globalement (par ex.
`http://www.example.org/home.html`).

French translation added.
