[Bug] 为什么在InputField的prefix失效了

[evanyue-fish]

What happened?

之前使用prefix，question = dspy.InputField(prefix='my_quetion')

执行后，实际上提示词还是使用question而不是my_quetion

Steps to reproduce

class tt(dspy.Signature):
"""回答问题"""
q = dspy.InputField(prefix='question')
a = dspy.OutputField()
i = dspy.Predict(tt)
pre = i(q='花的颜色有多少种')
pre

实际上还是q，而不是question

System message:

Your input fields are:

1. q (str)

Your output fields are:

1. a (str)

All interactions will be structured in the following way, with the appropriate values filled in.

[[ ## q ## ]]
{q}

Yes, prefix is not used by the adapters since DSPy 2.5+
