docs: In some rare cases you need to post process the placeholder data and add additional, global data to the route
      object. Define your post-processor in the DJANGOCMS_SPA_VUE_JS_PLACEHOLDER_DATA_POST_PROCESSOR setting variable
      (e.g. `my_app.my_module.my_function` and return the data you need.
