docs: Update Milvus feature table (#31472)

We found the [table of langchain milvus
feature](https://python.langchain.com/docs/integrations/vectorstores/)
is not consistent with the currently implemented code. So we change it
with a PR.

- searchByVector: code is
[here](e29ff1bff5/libs/milvus/langchain_milvus/vectorstores/milvus.py (L1543))
- passesStandardTests: All methods will be tested(including unittest and
integration test) , see an example [here](
https://github.com/langchain-ai/langchain-milvus/actions/runs/15347213828/job/43186093988)
, the test code it
[here](https://github.com/langchain-ai/langchain-milvus/tree/main/libs/milvus/tests)
and the github workflow is defined
[here](https://github.com/langchain-ai/langchain-milvus/blob/main/.github/workflows/_test.yml)
- multiTenancy: milvus supports different kinds of [multi
tenancy](https://milvus.io/docs/multi_tenancy.md#Implement-Multi-tenancy),
they also implemented by langchain_milvus
- database level: specify the database name in
[connection_args](e29ff1bff5/libs/milvus/langchain_milvus/vectorstores/milvus.py (L374))
- collection level: specify the collection in [collection_name
param](e29ff1bff5/libs/milvus/langchain_milvus/vectorstores/milvus.py (L337))
- partition level: specify the [partition-related params
](e29ff1bff5/libs/milvus/langchain_milvus/vectorstores/milvus.py (L280))
- idsInAddDocuments: [add document
method](e29ff1bff5/libs/milvus/langchain_milvus/vectorstores/milvus.py (L2030))
supports ids param passed in( then passed to add_texts method
[here](e29ff1bff5/libs/milvus/langchain_milvus/vectorstores/milvus.py (L1102)))
