A redundant setting (or a possible typo) in the tutorial: snappyMultiRegionHeater

Hi,

In decomposeParDict of https://develop.openfoam.com/Development/OpenFOAM-plus/blob/c7969911bc736af70c14faa74496b8b7801baa91/tutorials/heatTransfer/chtMultiRegionFoam/snappyMultiRegionHeater/system/decomposeParDict

The following is written:

coeffs
{
    n       (2 2 1);
}

IMHO, it was forgotten to be deleted in one of the commits while changing the method from hierarchial to scotch.
