Can't load onnx pretrained model without pytorch model file

[darpleon]

Hi! I found a bug.

GLiNER.from_pretrained() raises FileNotFoundError when trying to load an onnx model.
Looking at the code of from_pretrained(), it checks for a pytorch model file before checking if load_onnx_model is set.
I think this check could be moved to the if not load_onnx_model: block.

I discovered the bug on v0.2.24, and it seems to have been introduced in v0.2.23.
