Add ChatTTS download stats

[NielsRogge]

This PR ensures download stats are working for https://huggingface.co/2Noise/ChatTTS.

To do:

• I assume the repo must have library_name: chat_tts in its metadata for this to work. Made a PR on the repo: https://huggingface.co/2Noise/ChatTTS/discussions/10

Thanks for the PR @NielsRogge! You can also add a code snippet by updating model-libraries-snippets.ts and importing it correctly in model-libraries.ts. This way users will see a "use in ChatTTS" button on the model page. Snippet would be more or less the same as in model card (to be adapted)

chat = ChatTTS.Chat()
chat.load_models(compile=False) # Set to True for better performance

# Define the text input for inference (Support Batching)
texts = [
    "So we found being competitive and collaborative was a huge way of staying motivated towards our goals, so one person to call when you fall off, one person who gets you back on then one person to actually do the activity with.",
    ]

# Perform inference and play the generated audio
wavs = chat.infer(texts)

(especially useful if you expect several repos to host ChatTTS models)

Approve, modulo the comment + the "should we add a snippet?" question.

Thanks for the opening this PR. I wasn't asked for a review, but reviewing it because Audio :)

Could you make sure to run the linter to pass the failing test?
