Filters the content of a FAQ Group.

The $faq_group variable is structured as the following example:

$faq_group = [
    'ID' => 1,
    'title' => My FAQ Group,
    'position' => 1, //position within the editor
    'faqs' => [12, 23, 34, 45, 56, ...], //FAQ IDs
    'views' => [ //Number of views per FAQ ID
        12 => 10, 
        2 => 8, 
        3 => 14, 
        4 => 5, 
        5 => 2, 
        ...
    ],
];

Usage example :

add_filter( 'joli_faq_seo_faq_group', function($faq_group){
    //Filter $faq_group array here
    $faq_group['faqs'][] = 77; //Adds the FAQ 77 to the group.
    return $faq_group;
});
