docs: Update langchain-openai package version in chat_token_usage_tracking (#24436)

Browse Source 
This PR updates docs to mention correct version of the
`langchain-openai` package required to use the `stream_usage` parameter.

As it can be noticed in the details of this [merge
commit](722c8f50ea),
that functionality is available only in `langchain-openai >= 0.1.9`
while docs state it's available in `langchain-openai >= 0.1.8`.
