Fix Julia 1.10 LTS: remove duplicate unconditional import

The unconditional import of calc_rosenbrock_differentiation on line 35
conflicts with the conditional @static if block below (lines 42-50).
On Julia 1.10, the registry version of OrdinaryDiffEqDifferentiation
doesn't export this function, so the unconditional import fails.
