Fix Gin toolbar toggle button

Actually I've never seen the toggle button anywhere before but the JS error in the console I get with the current RC1 of Gin + Gin Toolbar tells me that there should be a toggle. Which is currently raising the following error.

Uncaught TypeError: Cannot read properties of null (reading 'parentNode')
    at addButtonGin (VM492 frontend_editing.js:233:19)
    at Object.attach (VM492 frontend_editing.js:265:13)

    at HTMLDocument.listener (VM470 drupal.init.js:14:7)

Steps to reproduce after running the following multi-liner, create a new paragraph type and add it to any content type, create a node with that paragraph and visit front-end. Check console, the above error happens.

mkdir my-drupal9-site && \
cd my-drupal9-site && \
ddev config --project-type=drupal9 --docroot=web --create-docroot && \
ddev start && \
ddev composer create "drupal/recommended-project:^9" -y && \
ddev composer require drush/drush drupal/gin:@rc drupal/gin_toolbar:@rc drupal/admin_toolbar drupal/frontend_editing:@rc && \
