Override NVIDIA environment variable for CUDA 12.1 images

[bandish-shah]

What does this PR do?

NVIDIA has pushed new base images that seem to be missing forward compatibility in the NVIDIA_REQUIRE_CUDA env var. We are overriding it here specifically for the 12.1 images.

To Do:

• check 11.8 staging image for correct env var
• check 12.1 staging image for new env var
• test resulting 11.8 staging image can be run on r1z2
• test resulting 12.1 staging image can be run on r1z2
• [after merge] release new docker images

What issue(s) does this change relate to?

Related to #2722.
