fix(core): update prompts (#6738)

Update prompts:

When sending a message to openai, we actually send two messages.
There are two issues here:

1. the role in the first message shall be user or system
2. the content in the first message is not being interpolated at all.

```
[
  {
    role: "assistant",
    createdAt: "2024-04-27T06:30:34.820Z",
    params: {
      language: "French",
    },
    content: "You are a translation expert, please translate the following content into French, and only perform the translation action, keeping the translated content in the same format as the original content:\n\n          \"\"\"\"\n\n          \n\n          \"\"\"\"",
  },
  {
    role: "user",
    content: "Basic things you should know:",
    attachments: undefined,
    params: {
      language: "French",
    },
    createdAt: "2024-04-29T09:42:11.466Z",
  },
]
```

In this PR I removed `content` from prompts and let open ai use the second message (user) as the input.
