Allow Graph view refreshing using hotkey

The graph view presently doesn’t reload automatically, which is okay for most cases. However, there’s no way to even refresh it manually. If I have the graph open and I either press the hotkey to open the graph or the plugin button in sidebar to load it again, it does nothing. I think it’d be helpful if doing that refreshed it instead to update the links. Currently to refresh it, I have to open a random note to move out of the graph view, then open it again to emulate a reloading.
