update ahash and hashbrown (#8623)

# Objective

- Update `ahash` and `hashbrown`
- Alternative to #5700 and #7420

## Solution

- Update the dependencies

This is a breaking change because we were creating two fixed hashers
with
[`AHasher::new_with_keys`](https://docs.rs/ahash/0.7.6/ahash/struct.AHasher.html#method.new_with_keys),
which was a method that existed only for testing purpose and has been
removed from public.

I replaced it with
[`RandomState::with_seeds`](https://docs.rs/ahash/0.8.3/ahash/random_state/struct.RandomState.html#method.with_seeds)
which is the proper way to get a fixed hasher (see [this
table](https://docs.rs/ahash/0.8.3/ahash/random_state/struct.RandomState.html)).
This means that hashes won't be the same across versions

---

## Migration Guide

- If you were using hashes to an asset or using one of the fixed hasher
exposed by Bevy with a previous version, you will have to update the
hashes
