Outdated comment about std::hash::DefaultHasher being inaccessible

Summary

This comment in library/std/src/hash/random.rs says
Although its items are public and contain stability attributes, they can't actually be accessed outside this crate.

However, std::hash::DefaultHasher and RandomState are accessible since version 1.76 (feature = "std_hash_exports"). The comment predates that, so I suppose it's outdated and should be reworded or removed to avoid confusion.

Somewhat related: https://doc.rust-lang.org/std/index.html?search=DefaultHasher only shows std::collections::hash_map::DefaultHasher, while presumably it should also show std::hash::DefaultHasher. Please let me know if there's a better way to report that one, as I'm not sure what the best venue would be.

std::collections::hash_map::DefaultHasher, while presumably it should also show std::hash::DefaultHasher

The search engine is only supposed to show one path for any particular item.

@dbdr I think you are correct about these lines being wrong now: The random mod only contains two items which are both pub and which are both reexported since 1.76.0 as you said. My proposed fix would be to just remove these outdated comments.

Would you want to try to do that yourself or would you prefer if I did that?

@hkBst thanks for the confirmation. I'll submit a PR, happy to make a small contribution and learn about the process, in case I have the chance to do more in the future.
