Add a test case for a single dimension evaluation

[bugsz]

📑 Description

I provide a test case for the issue mentions in #89.
Specifically this is done by adding a dummy evaluator with only one goal evaluation dimension, and add a new option for the response_format in evaluator.
Besides, I use the same format as in real Sotopia simulation in testing, which makes the test case aligned with the actual evaluation.

By the way currently I am using assert False (so the current pytest is definitely not passing) to see the output. However, I do not know how to check if there is a reasoning part. Does anyone have an idea?

@XuhuiZhou Could you help check this? I think this is basically a prompting issue? Maybe by changing the description of the goal dimension, it should work better?

@bugsz @ProKil Okay I fixed this bug, basically, the original instruction is a bit ambiguous. But they somehow magically work when they stick together
