Two improvements in pipelines (#20449)

### Description
1. Update the image name to avoid docker image wouldn't be overwrite.
there was an mistake that variables.CUDA_VERSION_MAJOR is always empty

https://github.com/microsoft/onnxruntime/blob/14fcf0a52d61e6015f288cf70025ad62dec7ac85/tools/ci_build/github/azure-pipelines/stages/nuget-linux-cuda-packaging-stage.yml#L120
3. set one artifact name as variable to make the job rerunnable
