Subsections are skipped in course index highlighting

[HSOtago]

Hi there,

As the title suggests, take a look at the video below - this can be quite disorienting for our users.

Thanks, Harry

In lieu of making a PR I can provide this fix:

1. Add this method to {flexsections plugin dir}/amd/src/local/courseeditor/exporter.js:

   /**
    * Return a sorted list of all sections and cms items in the state.
    *
    * @param {Object} state the current state.
    * @returns {Array} all sections and cms items in the state.
    */
   allItemsArray(state) {
       const items = [];
       const sectionlist = state.course.sectionlist ?? [];
   
       const addCms = (sectioninfo) => {
           const cmlist = sectioninfo.cmlist ?? [];
           cmlist.forEach(cmid => {
               const cminfo = state.cm.get(cmid);
               items.push({type: 'cm', id: cminfo.id, url: cminfo.url});
           });
       };
       const addChildItems = (children) => {
           if (children && children.length) {
               for (let i = 0; i < children.length; i++) {
                   const child = children[i];
                   items.push({type: 'section', id: child.id, url: child.sectionurl});
                   addCms(child);
                   addChildItems(child.children);
               }
           }
       };
       sectionlist.forEach(sectionid => {
           const sectioninfo = state.section.get(sectionid);
           items.push({type: 'section', id: sectioninfo.id, url: sectioninfo.sectionurl});
           addCms(sectioninfo);
           addChildItems(sectioninfo.children);
       });
       return items;
   }

2. Run grunt amd inside the plugin {flexsections plugin dir}/amd directory (make sure you ran npm install in moodle's root)
