Add model/datasets viewer for leaderboard

[Samoed]

Description of the feature

We can add viewer for model and datasets metadata information on different page on the leaderboard. We're filling a lot of information for them, but they're hidden from the users.

Also we can show models results in its own tab with different parameters (#1211, #2832) and have only one main result on leaderboard

This sounds great, @Samoed, but I think it doesn't fit on the leaderboard. Some of the model comparison space is a good idea. Like: mteb/model_comparison
