replace axios with fetch

[dominiksipowicz]

Describe the feature or improvement you're requesting

• Axios is not compatible with other runtimes (for example Edge).
• Significant reduction in size
• Fetch support for all runtimes (browser, node, edge, deno, workers)
• The fetch lib could optionally be passed as a dependency

Additional context

When running current version with axios on the Edge I got this error:

An error occurred during OpenAI request [TypeError: adapter is not a function]

Wow, that was quick. This is a great start. At this point, I just call directly REST endpoints with native fetch so it's a super nice thing to have!

Hi all, we have an upcoming version v4.0.0 that uses fetch and works on Edge runtimes; please give it a try and let us know in the thread whether it suits your needs!
