Vous êtes dans l'état « HEAD détachée ». Vous pouvez visiter, faire des modifications
expérimentales et les valider. Il vous suffit de faire un autre basculement pour
abandonner les commits que vous faites dans cet état sans impacter les autres branches

Si vous voulez créer une nouvelle branche pour conserver les commits que vous créez,
il vous suffit d'utiliser l'option -c de la commande switch comme ceci :

  git switch -c <nom-de-la-nouvelle-branche>

Ou annuler cette opération avec :

  git switch -

Désactivez ce conseil en renseignant la variable de configuration advice.detachedHead à false
