docs: `alibaba cloud` (#14772)
The [provider page](https://python.langchain.com/docs/integrations/providers/alibabacloud_opensearch) holds the vector store information. The [Chat example](https://python.langchain.com/docs/integrations/chat/pai_eas_chat_endpoint) was incorrectly sorted in the navbar because of the wrong file name. - Recreated a provide page - Added missed links and descriptions - Compound information about vector store from two pages into one - Fixed file namepull/14972/head
