refactor(documentation-website): cleanup faq item (#779) (#1017)

Fix "Non-interactive elements should not be assigned mouse or keyboard event listeners."
Fix "Use <input type="button">, <input type="image">, <input type="reset">, <input type="submit">, or <button> instead of the "button" role to ensure accessibility across all devices."
Fix "Elements with the 'button' interactive role must be focusable."
Fix "Visible, non-interactive elements with click handlers must have at least one keyboard listener."
