PR Summary

• Enhancement of the Accordion Class The Accordion class now has a new property: $headerToggleOptions. This allows for the customization of HTML options for the header toggle tag, providing more flexibility for users. The default options are a 'h5' tag and a 'mb-0' class.

• Update to the renderItem Method We've updated how the renderItem method in Accordion class works. It now uses the $headerToggleOptions property to create the header toggle tag in every item. This means each part of the list can have its own unique look and feel, further improving the class's flexibility.

• Testing of New Property and Functionality A new test, testHeaderToggleTag, has been added to ensure that the $headerToggleOptions property and the updated renderItem method are working as expected. This provides added assurance that these additions to the class are tested and validated, ensuring smooth, reliable performance for users.
