Solution for "Unsupported file type" error after recent project update

[harmlessman]

I wanted to hear the voice of the model I made after a long time, so I updated the project and tried voice synthesis. However, the following error occurred.

The reason for the error is that the type d_vector_file changed from str to list[str].

Let's change d_vector_file value to list value in config.
d_vector_file : "path" => d_vector_file : ["path"]

thank you.
