fix: IFEval dataset introduces the correct langdetect expectation path

[catohzs]

Motivation

When I tested the IFEval dataset locally, I found that this error would occur during the evaluation.

Traceback (most recent call last):
File "C:\Users\12072.projects\PyCharmProjects\evaluation\executor\opencompass\opencompass\tasks\openicl_eval.py", line 364, in
inferencer.run()

except langdetect.LangDetectException as e:
AttributeError: module 'langdetect' has no attribute 'LangDetectException'. Did you mean: 'lang_detect_exception'?

This seems to be caused by introducing the wrong path

Modification

I modified this path to be correct to avoid the problem of evaluation failure.

I can successfully import LangDetectException on linux by:

from langdetect import LangDetectException
