Breaking change in v4.91 — embeddings API

[kenn]

Confirm this is a Node library issue and not an underlying OpenAI API issue

• This is an issue with the Node library

Describe the bug

After updating from v4.90.0 to v4.91.0, the response from embeddings API is broken.

v4.90.0...v4.91.0

Note that it also ignores the dimensions parameter — I'm setting 256 but it returns text-embedding-3-large's full size, 2048.

Thanks for the report and very sorry for the regression. Working on a fix.
