/**
* Assign linked posts managed by The Events Calendar a language.
*
* We use the filter as an action to assign linked posts a language.
* WPML will not "see" posts that have not a language assigned: here we make sure that linked posts like
* venues and organizers will be assigned the language of the event they are being linked to.
*
* @param int $id The linked post ID; this would be `null` by default but we know TEC is inserting
* the post at priority 10.
* @param array $data Unused, an array of data representing the linked post submission.
* @param string $linked_post_type The linked post type, e.g. `tribe_venue` or `tribe_organizer`.
* @param string $post_status Unused, the linked post type post status.
* @param int $event_id The post ID of the event this post is linked to; this will be null for newly created events.
*
* @return int The untouched linked post ID.
