MAX_TOKEN needs to be parameterized to support various models

[Geoffrey Hung]

Describe the bug

https://github.com/sqlchat/sqlchat/blob/main/src/components/ConversationView/index.tsx#L26-L28
Currently, the MAX_TOKEN is hardcoded as 4000, which is almost the context limit of gpt-3.5-turbo [4096]

However, GPT4 can support 8192 tokens, which is double the MAX_TOKEN, the app can handle larger context in GPT4 if MAX_TOKEN is adjusted accordingly

To reproduce

As above
