More models needed for DashScopeEmbeddings

• I've clearly described the feature request and motivation for it

Feature request

DashScopeEmbeddings now only supports text-embedding v1 and text-embedding v2. But in fact tongyi has introduced more powerful models text-embedding-async-v1 and text-embedding-async-v2, which can support larger quantities of vector computation. Can langchain support new models in DashScopeEmbeddings?

Motivation

When I try to use text-embedding async-v1 in DashScopeEmbeddings, I find it is unsupported. I receive error info as follows when I set model to be "text-embedding-async-v1":
status_code: 400
code: InvalidParameter
message: input.url should not be null
