Typo in migration guide: EntityHashSet -> HashSet

[guyguy2001]

In the 0.15->0.16 migration guide, it says to use the following code:
(https://bevyengine.org/learn/migration-guides/0-15-to-0-16/#don-t-re-export-entityhashset-and-entityhashmap)

use bevy::ecs::entity::{hash_set::HashSet, hash_map::HashMap};

However, I get an error using it:

After finding https://bevyengine.org/learn/migration-guides/0-15-to-0-16/#bevy-utils-refactor, I now realize that the section in the docs I linked to was meant for EntityHashSet, and not HashSet, which threw me for a loop.

Also, it isn't clear that bevy_platform::collections means bevy::platform_support::collections in userland (I'm not actually sure what bevy_platform is, as I'm writing this - I assume it's the folder in the bevy repo)

Should I make an issue about that? Or is it the intended way to present it?
