Description: 

When using addItemToToolbar in a recipe, currently you can only add a single toolbar item to CKEditor within one recipe. Example:

name: Add specialCharacters to Rich Editor
description: 'A recipe to add specialCharacters to the Rich Editor with CKEditor 5'
config:
  actions:
    editor.editor.full_html:
      addItemToToolbar:
        item_name: 'specialCharacters'

Drupal core now supports using addItemToToolbar or its alias addItemsToToolbar to add multiple items to the CKEditor toolbar. Example:

name: Add specialCharacters and codeBlock to Rich Editor
description: 'A recipe to add specialCharacters and codeBlock to the Rich Editor with CKEditor 5'
config:
  actions:
    editor.editor.full_html:
      addItemsToToolbar:
        - specialCharacters
        - codeBlock
