8620 ModuleNotFoundError: No module named \'onnxscript\' in test-py3x (3.11) pipeline (#8621)

Fixes #8620 

### Description

On October 8th, there was a new release of the ONNX library
([1.19.1](https://github.com/onnx/onnx/tree/v1.19.1)).
Looking into previous versions of our CICD, which run successfully, the
errors coincide with that date. For example, [this
one](https://github.com/Project-MONAI/MONAI/actions/runs/18153916782/job/51669624135#logs)
was ok with onnx 1.19.0.

[This issue](onnx/onnx#7257) in the ONNX
project suggests that there were some recent breaking changes. This is
not exactly our issue, but it suggests that there may be something
similar going on.

I have added the condition `<1.19.1; python == 3.11` to prevent updates
on this Python version, since our original issue referred to Python
3.11.
It may be that this affects other versions. Let's see if the pipelines
execute successfully.
