fyi the azure team is working on a dedicated integration package, so we may still close this such that their team can release it there all together

will let you know whether they want to move forward with community first! If so, it would be great to get docs added

(also looks like there's a set of CI failures to look at that will prevent merging regardless)

closing in favor of work there - langchain-azure-ai is now out and would recommend trying AzureAIEmbeddingsModel from there!
