Description

We should be able to create Windows and Ubuntu nodegroups with NVIDIA GPU instances, which is why we
are removing the previously configured error for this scenario. However, we will log a warning as these AMIs don't ship with GPU drivers installed and we don't want give the illusion that running GPU-accelerated workloads will work out of the box.

Fixes #5256
