ToolBar open event should be described properly in typescript definition and API

[nelito987]

Bug report

Currently, it is documented that the e.SplitButton can be accessed in the Toolbar open event. And in the typescript definition - link
However, the SplitButton property is not set in the open event code.

Reproduction of the problem

1. Open the Dojo and check the result in the console.

Current behavior

The e.SplitButton is undefined

Expected/desired behavior

SplitButton element should be returned or we should fix the typescript definition.

Environment

• Kendo UI version: 2023.3.1114
• Browser: all

After reviewing the issue, we considered that the appropriate approach is to change the description in the APi. The item returned in the open/close event handlers may not be limited to the SplitButton—it could also be a DropDownButton, for instance. It is the returned component that is opened/closed.
