Move render-blocking EpiserverForms JavaScript out of document head

Google PageSpeed Insights reports the WebResource.axd containing the Episerver injected JavaScript in the page head is render-blocking. jQuery here, loaded as a dependency of the Episerver Forms js blocks page rendering by an estimated 300ms diminishing the sites Lighthouse and Web vitals scoring.
Splitting up the Episerver forms CSS and JavaScript dependencies will allow me to place the JavaScript in the bottom of the document body improving the percieved performance of the site significantly, and help me recommend Optimizely as a performant platform.
