* Add a settings listener that will be invoked whenever the desired setting is updated

* whenever Unindent is toggled. Pass an empty string to get notified for all changes
* @param onUpdate Callback function whenever a setting matching path is updated. It gets passed the new value and the path
* to the updated setting. This path will be the same as your path argument, unless it was an empty string.
*
* @example addSettingsListener("", (newValue, path) => console.log(`${path} is now ${newValue}`))
* addSettingsListener("plugins.Unindent.enabled", v => console.log("Unindent is now", v ? "enabled" : "disabled"))
