Improving the benchopt website

I always have a hard time finding the results of a benchmark. When I finally get to the [results page](https://benchopt.github.io/results/), some links are broken ("neurips 22 benchopt results"), and some benchmarks are not referenced there (e.g. [this one](https://benchopt.github.io/results/benchmark_resnet_classif.html)).

For now, the [home page](https://benchopt.github.io/index.html#) focuses on running an existing benchmark. I feel like this is just a very specific way to use benchopt. Could it be improved by being simpler and yet more comprehensive?

One idea to do this: instead of having a rather long home page as it is now, with information hidden all over the place (in the text, in the sidebar, etc.), just put simple access buttons:
- "Run an existing benchmark"
- "Access benchmark results"
- "Access benchmark source codes"
- "Add your own benchmark"
- ... (list all the other ways to use benchopt)

and an isolated button for the user who just wants to discover benchopt, redirecting the user to a high-level description of benchopt?

I know it's very subjective, but I think it might be worth discussing.
