Allow the display of different groups of suggestions depending on the language

[dtrucs]

With this PR there is now another way to display different suggestions group depending on the language

By setting an object with the languages code as keys instead of an array. By this way you can optimize the valorization of a territory according to the selected language. If you don't need this feature (or if you want the same configuration for several language), use default key instead of a language code. The configuration in the example below displays 2 groups of suggestions for all languages except the English version with one different:

"suggestions": {
  "default": [
    {
      "titleTranslationId": "home.territoryTreks",
      "iconUrl": "/icons/practice-pedestrian.svg",
      "ids": ["2", "582", "586", "501", "771", "596"],
      "type": "trek"
    },
    {
      "titleTranslationId": "home.events",
      "iconUrl": "/icons/category-events.svg",
      "ids": ["1", "5"],
      "type": "events"
    },
  ],
  "en": [
    {
      "titleTranslationId": "home.treksDiscovery",
      "iconUrl": "/icons/pedestrian.svg",
      "ids": ["2", "582", "586"],
      "type": "trek"
    },
  ]
}

For backward compatibility you can still use an array, this is the same behavior that object with only a default key. For example:

"suggestions": [
  {
    "titleTranslationId": "home.territoryTreks",
    "iconUrl": "/icons/practice-pedestrian.svg",
    "ids": ["2", "582", "586", "501", "771", "596"],
    "type": "trek"
  },
  {
    "titleTranslationId": "home.events",
    "iconUrl": "/icons/category-events.svg",
    "ids": ["1", "5"],
    "type": "events"
  },
]

OK c'est un peu complexe et discutable comme fonctionnalité, mais pourquoi pas.

[camillemonchicourt]

Pourquoi donner les 2 méthodes, ça complique les choses.
Alors que la seconde méthode est dépréciée ?

[dtrucs]

Indeed, i changed the documentation 👍

[camillemonchicourt]

"By this way you can optimize the valorization..." à remplacer par "By this way you can differentiate the valorization..."
C'est pas forcément de l'optimisation... Mais uniquement de différencier les suggestions en fonction de la langue.

[dtrucs]

Done 👍

[camillemonchicourt]

On devrait aussi modifier le fichier d'exemple (https://github.com/GeotrekCE/Geotrek-rando-v3/blob/main/frontend/customization/config/home.json) pour mettre la nouvelle méthode d'écriture des suggestions, avec juste un bloc "default".

[camillemonchicourt]

OK merci pour les modifications.
La PR doit aussi inclure la mise à jour de https://github.com/GeotrekCE/Geotrek-rando-v3/blob/main/frontend/customization/config/home.json avec le bloc default.
