Enable fallback locale on a per model basis

[yoeriboven]

In our project we use this package on multiple models. Almost all of them need a fallback language except a new one. We access the attribute using $model->translatableAttribute but this always uses the fallback language.

PR adds the possibility to add a useFallbackLocale property to the model.

class Article extends Model
{
    use HasTranslations;

    protected $useFallbackLocale = false;
}

This was my solution without this PR:

Translatable::fallback(missingKeyCallback: function (
    Model $model,
    string $translationKey,
    string $locale,
    string $fallbackTranslation,
    string $fallbackLocale,
) {
    if ($model instanceof NewsNotification) {
        return '';
    }

    return $fallbackTranslation;
});

Feels like a lot of code to disable fallback language.

Could you document this in the readme with a clear example?

Hope the docs are good. It's quite simple so let me know if you want me to add something.

We need this for a notification with a title and a CTA (simplified). Maybe the Dutch notification has only a title (the button/CTA would be optional) but the English notification has a title and CTA.

In that case Dutch users would see the Dutch title with the English CTA even though they should not see the button.

Thanks!
