Jonas Jenwald 8129815538 Enable the unicorn/prefer-dom-node-append ESLint plugin rule
This rule will help enforce slightly shorter code, especially since you can insert multiple elements at once, and according to MDN `Element.append()` is available in all browsers that we currently support.

Please find additional information here:
