Bump nvidia cuda docker image version

[stronk-dev]

Old version was removed, docker builds require a version bump. Not sure if this breaks anything

I see that it increased the Docker image size from 1.29GB to 2.38GB. Isn't that an issue? CC: @thomshutt @hjpotter92

image sizes aren't a problem now. we are provisioning our machines to use the entire SSD storage; instead of earlier 50GB as / partition and rest as /data. each server now has atleast 500GB of disk space to store docker images in cache and the persitant storage is handled separately (if needed).

@hjpotter92 that's true, but it still makes it more unwieldy to work with, slower to build etc. and so if there is a way to keep it down then that's probably worth exploring

I see the version 12.x is small, so we may upgrade to it. Just need to think how to test it.

I believe the last time this was discussed, @iameli raised an issue with ubuntu18.04 also getting bumped. if we're planning to keep ubuntu18.04 as the supported runtime version, we should go with 11.6.2 as that has the smallest image size.

however, if we're also planning to ditch the now EOL-ed ubuntu18.04, should we also consider ubuntu20? I believe when we reprovisioned our infra, the machines were installed with ubuntu20 (and that had been the concern last time this image was bumped).
