MTT-7858: Make ParrelSync window interactable in tutorial

[Elfi0Kuhndorf]

Description

The last page of the Data and event synchronization tutorial of MultiplayerUseCases sample tells the user that they can use ParrelSync, but the ParrelSync window was not interactable due to IET masking.

The masking settings of that tutorial page were adjusted so that users can use the ParrelSync window in the last step of the tutorial.

Tested the changes on Mac, and on that last step I'm able to interact with the Menu item to bring up a ParrelSync window, and when it opens it is highlighted by IETs.

An open question, is it possible to have the IET open the ParrelSync window once you get to that last step? @RikuTheFuffs

@fernando-cortez Should be possible if the ParrelSync window type is public and accessible from IET.
Every tutorial page has soem custom callbacks you can use for this: ("Shown" would be the appropriate one)
