chore(Bing): update turbo availability in Readme

[Richard-Weiss]

This PR resolves #6.
At the current time GPT-4 Turbo is only available with the Copilot Pro subscription.
Passing the model version without the subscription will lead to the system using the default model anyway.

Sorry, I provided some misinformation before. Actually, those options related to GPT-4 Turbo are deprecated. And I was tricked by a specific implementation of SydneyQt, where we use MessageType=SearchQuery to double the daily quota. But it also caused GPT-4 Turbo not being used even for Copilot Pro users.

For Copilot Pro users, to decide whether GPT-4 Turbo is used, we specify tone. Creative means GPT-4 Turbo and CreativeClassic stands for GPT-4.

I've uploaded the parameters used to create conversations:

No offense, but that doesn't sound right.
For example in vanilla Bing tone is set to Creative and I'm pretty sure it's not Turbo from my experience and other reports how Turbo behaves.
Also capabilities are almost always managed by the optionSet, including the persona, toneStyle like creative, balanced, precise and other capabilities.
I'll just leave the Readme like that until Custom GPTs drop so I'll try Copilot Pro and reproduce having Turbo on a paid and free account.

This is due to the type of account. For paid customers, Creative corresponds to GPT-4 Turbo, while CreativeClassic indicates GPT-4.

I've tested this on both paid and free accounts. I found that setting the tone to Creative is the only requirement to enable GPT-4 Turbo for Copilot Pro users. However, this does not enable GPT-4 Turbo for free users.

How do you differentiate between GPT-4 and GPT-4 Turbo?
I mean how are you certain it's either one?

I tested it by asking what the Bun runtime is and which programming language was used to develop it. If it correctly identifies that Bun is a JavaScript runtime written in Zig, then I conclude it's GPT-4 Turbo.
