Add prompt configuration information to each question for the chatgpt-based bot

[cab938]

We need a new table/area called "Agent Instructions" which is a per-question prompt and an agent name (e.g. "chatgpt_repair").

The goal is to be able to capture information needed by this file:

https://github.com/machine-teaching-group/gpt-hints-api-202405-app/blob/master/feedback_generation/utils/gpt4hints_gpt35val/config.json

Specifically, contextual information to constrain or guide the chatgpt (or other) agents, like this:

"resources": "Resources:\nYou are only allowed to use the built-in Python modules (in particular, you are expected to use the re module). Don't use other libraries.",

Let's design this and see what a good solution would be.
