bump cuda to 12-8 (opendatahub-io#223)

This bumps the cuda version in the base layer to 12-8 instead of 12-4.
This could break something if during dep install
we have to build a dependency from source, as the wheels we bring in
later in prepare are now being built against 12.8.

FIX #xxxx (*link existing issues this PR will resolve*)
