.accordion-icon gets added by JS even if we don't want or need it

[AWearring]

We have our own Accordion twig files to add our preferred Font Awesome icons to the accordion panes we therefore don't want or need <span class='accordion-icon' aria-hidden='true'></span> that gets added to the DOM in modules/localgov_subsites_paragraphs/js/localgov-accordion.js

Could these icons not be added via the twig file modules/localgov_subsites_paragraphs/templates/paragraph--localgov-accordion-pane.html.twig instead of using JS?
