RHOAIENG-38635: add build-args for CUDA and CPU images for RStudio Python 3.11

• RHOAIENG-38635: add the Dockerfile.konflux files for RStudio as they are right now on rhds/main to allow for konflux onboarding #1725

Description

https://redhat-internal.slack.com/archives/C05NXTEHLGY/p1763706017709829?thread_ts=1762876200.999629&cid=C05NXTEHLGY

How Has This Been Tested?

Self checklist (all need to be checked):

• Ensure that you have run make test (gmake on macOS) before asking for review
• Changes to everything except Dockerfile.konflux files should be done in odh/notebooks and automatically synced to rhds/notebooks. For Konflux-specific changes, modify Dockerfile.konflux files directly in rhds/notebooks as these require special attention in the downstream repository and flow to the upcoming RHOAI release.

Merge criteria:

• The commits are squashed in a cohesive manner and have meaningful messages.
• Testing instructions have been added in the PR body (for PRs involving changes that are not immediately obvious).
• The developer has manually tested the changes and verified that the changes work
