Fix example of "Datalist (auto complete) - Dynamic" polyfill (#9065)

* Update datalist-dynamic-en.hbs

Corrects the example code

* Update datalist_dynamic.js

Corrects code by updating AJAX URL with correct GitHub issue prefix (was "Plugin: ", now "Feature: ")

* Update datalist-dynamic-fr.hbs

Correct French example code
