velocity damping description not up-to-date

Hi,

I'd just realized that the velocity damping header file description is not up-to-date https://develop.openfoam.com/Development/OpenFOAM-plus/blob/master/src/fvOptions/constraints/derived/velocityDampingConstraint/velocityDampingConstraint.H

It should be: ` damp { type velocityDampingConstraint; active true;

velocityDampingConstraintCoeffs
{
     UMax           25;
     selectionMode  all;
     // Optional: name of velocity field (default: U)
     //UName       U;
}

} `

Best, Sebastien
