[BUG] Cohere API requires array of strings for stop sequence

[elebumm]

Describe the bug
When you insert a Cohere API key, it gives an error when trying to use the LLM saying:

 Retrying langchain_community.llms.cohere.acompletion_with_retry.<locals>._completion_with_retry in 4.0 seconds as it raised CohereAPIError: invalid type: parameter stop_sequences is of type string but should be of type []Object.

To Reproduce

1. Insert Cohere API key
2. Use the LLM
3. Check console.

Expected behavior
A response, instead it gets hungup with a langchain error.

Additional context
I believe it's because Cheshire Cat is sending just a string instead of an array of strings.

Hi, thanks for address the issue.
The error seems related to a deprecated version of the class we use to interact with cohere, and a PR is already open to fix the problem.
Sorry for the incontinence but langchain is evolving to fast and we don't XD

We pushed a new version of the cat -> 1.6.2 and should work just fine
