add hover implementation to graph_objs.Indicator

Following the hovering tutorial for Dash Tooltips, I noticed that the described hovering functionality present in graph_objs.Scatter is not present in graph_objs.Indicator (I get Invalid property specified errors for hoverinfo, and the callback does not fire)

I respectfully request this functionality be extended to the Indicator and thank you in advance for your consideration.

For context behind my request, I am building a dashboard for my workplace that will be used internally and will auto-configure based on the job that is running. The user being able to hover over the graph and view extra context as to what it is displaying would be highly beneficial.

Commencez par comparer le comportement de survol décrit pour graph_objs.Scatter avec l’objet graph_objs.Indicator, en utilisant le Dash Tooltips tutorial comme comportement attendu. Confirmez l’erreur actuelle « Invalid property specified » et le comportement du callback, puis vérifiez que Indicator prend en charge le contexte de survol demandé sans perturber la validation existante des objets graphiques.
