let me take a look @connorchenn

@connorchenn Could you edit the mapping file instead of manually mapping them in the code? For cleaner practices.

info["glm-4-air"] = {
        "display": "GLM-4-Air",
        "link": "https://open.bigmodel.cn/",
        "org": "Zhipu AI",
    }

    }

@connorchenn Thank you so much! A few things:

1. Add arena-hard ranking to full leaderboard table
2. Add knowledge cuff off to the the arena hard leaderboard
3. Add last updated to the csv file and support automatic update in the title
4. Update the element id for the leaderboard.
5. Add link to paper in title.
6. Update Llama-3 score on Arena Hard Repo.

And we should be good for merging.

@connorchenn I think this looks good pretty much. Just one thing, the column name for arena-hard-auto is too crammed. Let's change it to arena-hard-auto and make the space for the column name larger so it fits in one line?

@connorchenn Could you fix the code format? It is not passing the check.
