1b19d6f4 - torch-light: add executorch (+onnx) for CPU exporter tests

torch-light: add executorch (+onnx) for CPU exporter tests Install onnxscript + onnxruntime and executorch==1.2.0 in the CPU test image so the CPU-only exporter tests (tests/exporters, executorch tests marked require_non_gpu) can run here. executorch 1.2.0 matches transformers' exporter API (targets 1.3.1) and requires torch>=2.11.0, satisfied by the torch<=2.11.0 pin already present.
