chore: remove openai JSON schema (instill-ai#260)

Because

- Previously, we downloaded the OpenAPI schema from OpenAI and
referenced it, but this approach isn't ideal as some descriptions might
differ.

This commit

- Removes the OpenAI JSON schema and directly writes the schema in our
JSON schema.

 | System message | `system-message` | string | The system message helps set the behavior of the assistant. For example, you can modify the personality of the assistant or provide specific instructions about how it should behave throughout the conversation. By default, the model’s behavior is using a generic message as "You are a helpful assistant." |

Please note that System Message will be ignored and will not have any effect when this field is populated. Each message should adhere to the format \{"role": "The message role, i.e. 'system', 'user' or 'assistant'", "content": "message content"\}. |

-| Max Tokens | `max-tokens` | integer | The maximum number of <a href="/tokenizer">tokens</a> that can be generated in the chat completion.  The total length of input tokens and generated tokens is limited by the model's context length. <a href="https://cookbook.openai.com/examples/how_to_count_tokens_with_tiktoken">Example Python code</a> for counting tokens.  |

 | Top P | `top-p` | number | An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered.  We generally recommend altering this or `temperature` but not both.  |
