Fix: show check highlight for spectators by passing interactiveBoardParams in TvScreen

[Sanket-Kurle]

I updated tv_screen.dart to properly configure the chessboard in spectator mode.
Added interactiveBoardParams with PlayerSide.none

this is solution for issue #2128

[Sanket-Kurle]

@HaonRekcef have you seen these changes
are they same as you suggested

[HaonRekcef]

Yes looks good to me thanks! Did you test them in a real game as a spectator?

[Sanket-Kurle]

not in real game

I see the changes. I don't understand the Spectator Check Demo screenshot though. It does not come from the app, it is not really useful then.

I don't really like passing interactiveBoard params to a board that is not supposed to be interactive. To me the missing check highlight in the TV is not a big deal in any case.
