Mac runners segmentation fault on pin updates

The pin updates in https://github.com/huggingface/optimum-executorch/pull/117 cause a segmentation fault / bus error on all mac tests when running forward on the loaded pte, regardless of model size. A few folks have taken a look but we'll likely need someone to dive in deep to figure this one out.

Example segmentation fault error: https://github.com/huggingface/optimum-executorch/actions/runs/16973422485/job/48116076576
Example bus error: https://github.com/huggingface/optimum-executorch/actions/runs/16973422485/job/48116076175

The mac test have current been commented out, this issue is to fix the model forward error and re-enable the tests.
