[Bug] IconClassToClose or IconClassToOpen not specified

[wartek69]

Describe the bug I'm getting the following while trying to use a submenu.

crit: Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
      Unhandled exception rendering component: IconClassToClose or IconClassToOpen not specified
System.ArgumentException: IconClassToClose or IconClassToOpen not specified
   at Blazored.Menu.BlazoredSubMenuBase.OnParametersSet()
   at Microsoft.AspNetCore.Components.ComponentBase.CallOnParametersSetAsync()
   at Microsoft.AspNetCore.Components.ComponentBase.RunInitAndSetParametersAsync()

I just followed the readme to import the library in a .net7 app using webassembly.

I'm getting it targeting .net6 in a Blazor Server app
