Change module integration imports from langchain-community to langchain-*

Feature request

Currently the init file in any integration type is imported from the langchain-community package
for example, vector stores are all imported from this package
Many of those integrations are deprecated, e.g. Milvus vector store should be imported from langchain-milvus, at this point all official documentation are pointing to the newer package

At this moment, when any vector store is imported with:
from langchain.vectorstores import Milvus
The deprecated module is imported by default, this should be fixed to import from the correct path.

Motivation

Importing from the wrong path imports outdated and unmaintained code which can cause a lot of compatibility and security issues.

As far as I understand, in order to fix, paths should be changed in the __init__ file and for each integration path, e.g. for the Milvus vectorstore file milvus.py
The code:

if TYPE_CHECKING:
    from langchain_community.vectorstores import Milvus

Should be changed to:

if TYPE_CHECKING:
    from langchain_milvus import Milvus
