Fix onnxruntime-gpu churn in Docker TensorRT FP8 install step#14

Conversation
nvidia-modelopt[onnx] (unbounded, floats to 0.45.0) hard-pins onnxruntime-gpu==1.22.0 on Windows and force-upgrades onnx to 1.21.0, which breaks FP8 quant (external-data loading -> negative QDQ scale). Pin modelopt==0.43.0 (the proven pin used by the installer's TD path) and drop the [onnx] extra, enumerating its deterministic deps explicitly instead — modelopt core has no onnx requirement, so the onnx==1.19.1/onnxruntime-gpu==1.24.4 pins installed just above are never perturbed. Mirrors the same fix landed in forkni/StreamDiffusion-installer#4. Co-Authored-By: Claude Opus 5 <[email protected]>
