Opset Issue while exporting to onnx

`UnsupportedOperatorError: Exporting the operator 'aten::scaled_dot_product_attention' to ONNX opset version 12 is not supported. Support for this operator was added in version 14, try exporting with this version.
`

The following code is used

```
from setfit import SetFitModel
model = SetFitModel._from_pretrained("setfit_model/")

from setfit.exporters.onnx import export_onnx
output_path = "model.onnx"
export_onnx(model.model_body,
model.model_head,
opset=12,
output_path=output_path)
```

Env:

```
torch = 2.4.1
setfit = 1.1.0
transformers = 4.45.1
onnxruntime = 1.19.2
onnx = 1.16.2
```

while trying to use opset version 14,

I get this error

`
