VectorStoreFileService.GetAsync() is not working as expected #219

Hello
It seems the implementation of VectorStoreFileService.GetAsync(VectorStoreFilesListRequest ) is not correct.
I am trying to retrieve list of files (FileData), attached to a vector store.

Issue 1. VectorStoreFilesListRequest does not contain property for VectorStoreId
Issue 2. VectorStoreFileService.GetAsync() returns list of vector stores, not the list of files.
