    Uploads data manually to the VectorDB.

    This function initializes a PrepareVectorDB instance with configuration parameters
    such as data_directory, persist_directory, embedding_model_engine, chunk_size,
    and chunk_overlap. It then checks if the VectorDB already exists in the specified
    persist_directory. If not, it calls the prepare_and_save_vectordb method to
    create and save the VectorDB. If the VectorDB already exists, a message is printed
    indicating its presence.
