createShortcut method fails in R2025b

I tried to create a shortcut in R2025b, but it raised an error—possibly due to changes in the API.

```
>> MBeautify.createShortcut('editorpage')
错误使用 [MBeautyShortcuts.createShortcut](matlab:matlab.lang.internal.introspective.errorDocCallback('MBeautyShortcuts.createShortcut', 'C:\Matlab_toolbox\MBeautifier\MBeautyShortcuts.m', 40)) ([第 40 行](matlab: opentoline('C:\Matlab_toolbox\MBeautifier\MBeautyShortcuts.m',40,0)))
