[Feature Request] Ability to select a OpenAI model

[gianpaj]

💭 Describe the feature

I think the default one is hardcoded to gpt-3.5-turbo

cz-git/packages/cz-git/src/generator/api.ts

Line 87 in b091c64

model: 'gpt-3.5-turbo',

💡 Proposed Solution

Be able to set the AI model in the czg command line
e.g.

czg --ai-model=gpt-4-1106-preview

Related but not the same as #102

As you can't specify the exact model.

GPT-4 turbo (gpt-4-1106-preview) is 66% cheaper than GPT-4 (gpt-4)

gpt-3.5-turbo-1106 costs $0.0010 / 1K tokens

But gpt-4-1106-preview is 1000% more expensive than gpt-3.5-turbo-1106 😬💰

Unfortunately, my openai api key has expired, and I can't renewal it, so the feature may not be landed in time.

Sure ~ PR Welcome 😉
