Summary
Drop the CUDA 12.1 container builds in favour of the already-available 12.9 images, and add CUDA 13.0 alongside Python 3.14 to the build matrix.
Motivation
Maintaining redundant CUDA 12.1 builds alongside 12.9 increases CI time and image storage without providing additional coverage. CUDA 13.0 is now available and should be adopted early to stay ahead of framework requirements. Ray has also started building image with Python 3.14, so we can start supporting that as well
