Moderation: migrate to new openai api

[CheeseDurger]

Fixes issue #13685 : OpenAIModerationChain still uses the old OpenAI API.

Description

The following snippet:

from langchain.chains import OpenAIModerationChain
from openai import moderations

print(OpenAIModerationChain(client=moderations).run("i want to kill you"))

Gives the following error :

Traceback (most recent call last):
  File "moderate.py", line 4, in <module>
    print(OpenAIModerationChain(client=moderations).run("i want to kill you"))

You tried to access openai.Moderation, but this is no longer supported in openai>=1.0.0 - see the README at https://github.com/openai/openai-python for the API.

You can run `openai migrate` to automatically upgrade your codebase to use the 1.0.0 interface.

Alternatively, you can pin your installation to the old version, e.g. `pip install openai==0.28`

A detailed migration guide is available here: https://github.com/openai/openai-python/discussions/742

can we try to do this in a way that is compatible with all versions of openai? see https://github.com/langchain-ai/langchain/pull/14222/files for inspiration

[CheeseDurger]

Should be compatible with v0 and v1, but reviews are appreciated.

[CheeseDurger]

@hwchase17 is it mergeable ?

We also need this fix urgently? Can this be merged? cc: @vaibhavbhuva

CheeseDurger, thanks for suggesting this fix for 13685.

I also wanted to comment to share I am eagerly awaiting a solution as well. Thanks all for coding & reviewing efforts!

[MrNickBreen]

CC @efriis, @eyurtsev, @nfcampos I see all of you have also successfully committed changes to this file and are associated with https://github.com/langchain-ai. Could you help @CheeseDurger with a review, more suggestions, or if appropriate, successfully merge this fix to continue to support OpenAI Moderation functionality?

[efriis]

unfortunately we can't do imports like this in langchain because of optional dependencies.

If you want to add this to the libs/partners/openai langchain_openai package, then you can rely on the v1 client there!
