feat: drop support for nvidia 470 (#227)

Due to the combination of Fedora F38/F39 upgrading to kernel 6.8 and
rpmfusion dropping support for nvidia 470 which does not compile on 6.8,
we have to drop our nvidia 470 images.

force-merged after all checks green because we need this to have any hope of clean builds in the morning.
