chore: fix format with nightly

Fix formatting with nightly.

Without nightly, some of our `rustfmt.toml` rules aren't applied because they are not stable yet (e.g. our `group_imports` rule).
Our CI didn't catch it yet because it doesn't check fmt on nightly. Will fix that in a follow-up PR.

Pull-Request: #5742.
