Fix SongGeneration download count rule (#1554)

Follow-up PR after
#1542 cc @juhayna-zh
@xianbaoqian @Vaibhavs10
There seems to be a typo in the download count rule. Checkpoint is saved
at
https://huggingface.co/tencent/SongGeneration/blob/main/ckpt/songgeneration_base/model.pt
(under `songgeneration_base`, not `songgeneration_base_zh`). This PR
fixes this.

(I also took the opportunity to update `repoName`, it's usually best if
it's the same as `prettyLabel`)
