[Bug]: [null & default] [milvus_client] there is no "default_value" value when describe collection for default_value set fields

[binbinlv]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

there is no "nullable" or "default_value" value when describe collection for nullable/default_value fields

{'field_id': 103, 'name': 'nullable_field', 'description': '', 'type': <DataType.INT64: 5>, 'params': {}}

Expected Behavior

there is "nullable" or "default_value" value when describe collection for nullable/default_value fields

Steps/Code To Reproduce behavior

schema = client.create_schema(enable_dynamic_field=False)
        schema.add_field("id_string", DataType.VARCHAR, max_length=64, is_primary=True, auto_id = False)
        schema.add_field("embeddings", DataType.FLOAT_VECTOR, dim=dim)
        schema.add_field("title", DataType.VARCHAR, max_length=64, is_partition_key=True)
        schema.add_field("nullable_field", DataType.INT64, nullable=True, default_value=10)
        schema.add_field("array_field", DataType.ARRAY, element_type=DataType.INT64, max_capacity=12, max_length=64, nullable=True)

Environment details

- Method of installation (Docker, or from source):

When change pymilvus to 2.5.0rc81, "nullable" exists in describe_collection, while "default_value" still not exists.

seems related with #2272
