Recent Jina update breaks vectordb initialization

[turner-anderson]

The 3.20.0 update on Jina introduced a few new positional arguments to _FunctionWithSchema including 'is_singleton_doc', 'parameters_is_pydantic_model', and 'paramaters_model'. This seems to have broken the initialization of at least the InMemoryExactNNVectorDB and HNSWVectorDB. When trying to create a db the following error message is generated:

 TypeError                                 Traceback (most recent call last)

       3 from vectordb import InMemoryExactNNVectorDB, HNSWVectorDB
       5 # Specify your workspace path
 ----> 6 db = InMemoryExactNNVectorDB[ToyDoc](workspace='./workspace_path')
       8 # Index a list of documents with random embeddings
       9 doc_list = [ToyDoc(text=f'toy doc {i}', embedding=np.random.rand(128)) for i in range(1000)]

 TypeError: _FunctionWithSchema.__new__() missing 3 required positional arguments: 'is_singleton_doc', 'parameters_is_pydantic_model', and 'parameters_model'

I fixed temporarily by reverting to Jina 3.19.0

Will fix soon
