14e738b5 - [tests] Skip onnx.exactness for BitForImageClassification (ORT fp32 drift) (#49366)

[tests] Skip onnx.exactness for BitForImageClassification (ORT fp32 drift) (#49366) `BitForImageClassification` was missing from `EXPORT_SKIPS["onnx.exactness"]` unlike its siblings `BitModel` and `BitBackbone`. The same ORT fp32 accumulation through the BiT conv stack drifts ~0.0013 on the logits, just over the 1e-3 tolerance, causing ~4-5% flaky failures.
