BREAKING: some env paramaters has been changed!
This commit adds support for multiple GPT models in the chatGPT-browser
client. The available models are now stored in a Map object, which maps
the model label to its corresponding model.
The commit adds a new component, ChatGPTOptions, to the client
UI to allow the user to select the GPT model to use in the chat. The
component is only displayed when the chatGPT-browser endpoint is
selected.
