feat(openai): support openai v5

[sabrenner]

What does this PR do?

With the release of OpenAI v5, the only thing we needed to account for was some del methods changing their name to delete. Otherwise, our instrumentation is largely unchanged.

This PR mostly fixes tests. There were a few things impacted:

1. We had to upgrade our nock dev dependency since OpenAI switched to using undici.Fetch under the hood instead of vanilla HTTP.
2. The beta feature we supported is only for OpenAI v4 and does not need to be tested for v5 (as it does not exist anymore)
3. There was a small File error, I think just on my machine which runs Node 18 by default - it likely won't impact CI as I think we run on latest but I wanted to handle it regardless.

Motivation

Support OpenAI v5 and unblock broken CI
