[DOC] Add LinkedIn Insight Tag

[Emanuel-Allely]

Insert the documentation link:
https://docs.luos.io/

Describe the issue or the suggestion:
Est-ce que tu pourrais coller l’Insight Tag ci-dessous dans le pied de page global de la doc, juste au-dessus de la balise de fermeture HTML ? En ajoutant ce tag dans le pied de page, je pourrais suivre les conversions ou procéder au reciblage des pages de mon choix pendant les campagnes d'ads LinkedIn.

How would you fix the issue / which content would you add or delete?
