Accordions runs outdated jQuery

I have noticed Accordions has stopped working for me. Specifically, there’s an outdated jQuery code being used:

jQuery(window).load(function() {

Which, as far as I know, should be substituted by:

$(window).on("load",function(){});

Is it possible to modify this so the plugin can run on newer jQuery versions? This isn’t going to work on further jQuery updates, so it should be fixed.
