Adding a limit param to the /api/papers/search api

[tleyden]

Is your feature request related to a problem? Please describe.

The list_papers api endpoint takes a single query parameter for a keyword search, but can return hundreds of results.

Here is the OpenAPI Playground docs for the endpoint:

https://huggingface-openapi.hf.space/#tag/papers/get/apipaperssearch

Describe the solution you'd like
At minimum, add a limit param to limit the search results. Without this, the amount of search results can be overwhelming for certain apps.

Describe alternatives you've considered
I can filter on the client side, however that is a waste of compute and bandwidth for both parties.

Additional context
I'm open to submitting a PR if someone will sign up to review it. Let me know the PR guidelines.

I'm building a mobile app and one of the features will be to easily navigate the Hugging Face Top Papers, and I want to base it on API calls rather than having to resort to web scraping.
