Fix not saving addItemToToolbar recipe action for divider | (vertical separator) or wrapping - items to CKEditor 5

Problem/Motivation

Not able to add a divider or a wrapping in CKEditor 5
Using recipes

Steps to reproduce

Scenario: Add a divider to the Rich Editor with CKEditor 5

Given having a recipe named "add-divider-to-rich-editor"
And the recipe.yml file in it has

name: Add Divider to Rich Editor
description: 'A recipe to add a divider as (vertical separator) to the Rich Editor with CKEditor 5'
type: optional
config:
  actions:
    editor.editor.full_html:
      addItemToToolbar:
        item_name: '|'

When I run php core/scripts/drupal recipe /recipes/add-divider-to-rich-editor
Then I get the following out put

[notice] A backup checkpoint was not created because nothing has changed since the "Backup before the 'Add Divider to Rich Editor' recipe." checkpoint was created.

Applied Add Divider to Rich Editor recipe.

                                                                                                                        
 [OK] Add Divider to Rich Editor applied successfully

But the divider was not added to the full_html text format

When I run php core/scripts/drupal recipe /recipes/add-wrapping-to-rich-editor
Then I get the following out put

[notice] A backup checkpoint was not created because nothing has changed since the "Backup before the 'Add Divider to Rich Editor' recipe." checkpoint was created.

Applied Add Wrapping to Rich Editor recipe.

                                                                                                                        
 [OK] Add Wrapping to Rich Editor applied successfully                                                                  
                                                                                                                        

But the wrapping was not added to the full_html text format

Proposed resolution

• Add save before return in the divider "|"
• Add support for the wrapper "-" with save before the return

Remaining tasks

• File an issue
