Won't lie, it bugs me a little that name is no longer the first key in this new format 😅

I guess it is better to have some defined order for keys, but can this be configured?

Unless others are fine with the default alphabetical 👍

Thanks for reviewing this @Jefffrey

I added a rule to skip reordering package table, it should look better now. Please check it out 😆

This broke /dev/rust-lint.sh because

/ci/scripts/rust_toml_fmt.sh isn't valid bash:

set -ex
taplo format
done <-- this should be removed.
