Fixes #1263

Changes

Move all the burn crates to their dedicated directory called crates.
We chose to keep the crate folder names to be the same as the actual crate name, see discussed in #1263

I'll update the links in the contributor book once this is merged.

Testing

run-checks and making sure our CI passes.

Fantastic! Perhaps we can add

members = [
  "crates/*",
]

to the main Cargo.toml instead of each single crate

I was wondering if it would be clearer to move examples crates, since they are independent, into a new burn repository such as the models repository.

[syl20bnr]

I updated the Cargo file with crates/*. 👍

We have no mechanism to publish examples alongside versions and they are using local crates from the repo. So for now it is better to keep them in the monorepo.

I would add we should keep in the same repository. It would be difficult to synchronize the versions

[Luni-4]

To synchronize the versions we just have to change from path to git since examples do not have to be published it should not be problematic moving them in another repository, but ok, no problem in leaving them here
