28bef6f8 - Clean up OpenAI Embeddings to fix method name and comments (#2687)

Clean up OpenAI Embeddings to fix method name and comments (#2687) **Problem:** OpenAI Embeddings has a few minor issues: method name and comment for _completion_with_retry seems to be a copypasta error and a few comments around usage of embedding_ctx_length seem to be incorrect. **Solution:** Clean up issues. --------- Co-authored-by: Vijay Rajaram <vrajaram3@gatech.edu>
