Narrow OrdinaryDiffEqDifferentiation 2.8 floor to OrdinaryDiffEqRosenbrock 1.30+ (#154175)

Narrow OrdinaryDiffEqDifferentiation 2.8 floor to Rosenbrock 1.30+

#154061 raised the OrdinaryDiffEqDifferentiation lower bound to 2.8
for the entire OrdinaryDiffEqRosenbrock 1.23-1 range, but the OOP
calc_rosenbrock_differentiation symbol that needs Differentiation
2.8.0 is only *called* starting in Rosenbrock 1.30.0
(SciML/OrdinaryDiffEq.jl#3075, version-bumped via dff8c622).

Versions 1.23.0-1.29.0 only call the bang variant
calc_rosenbrock_differentiation!, which exists in every 2.x of
Differentiation. Restoring the original "2" floor for that subrange
unblocks downstream packages that pin Rosenbrock in 1.23-1.29
without weakening protection for 1.30+.
