docs: use get_dataset_leaderboard in leaderboard guide (#2327)
* docs: use huggingface_hub get_dataset_leaderboard in leaderboard guide
Now that huggingface/huggingface_hub#3953 is merged, replace the raw
requests.get example with the typed get_dataset_leaderboard() method.
Also update response field names to match DatasetLeaderboardEntry
attributes and add cross-reference from eval-results page.

* docs: drop eval-results cross-reference per review feedback
Remove unnecessary cross-link from eval-results page since the
leaderboard guide is already adjacent in the nav.
