Remove CUDA/TensorRT providers from onnxruntime-node in managed runtime

linuxdeploy scans all ELF files in the AppDir and fails when it finds
libonnxruntime_providers_cuda.so which links to libcublasLt.so.12 — a
CUDA library not available on CI runners.

onnxruntime falls back to the CPU provider when CUDA is absent, so
removing these has no functional impact.
