[WARNING] Unexpected key(s) present on local => nixpkgs-fmt: types_or

[roberth]

With nixos-unstable, I'm getting warnings like these

[WARNING] Unexpected key(s) present on local => nixpkgs-fmt: types_or
[WARNING] Unexpected key(s) present on local => ormolu: types_or
[WARNING] Unexpected key(s) present on local => shellcheck: types_or

It appears that the configuration format has changed with a pre-commit update, or at least it has started checking for unknown fields.

And with nixfmt-rfc-style I'm now seeing on unstable

[WARNING] Unexpected key(s) present on local => nixfmt-rfc-style: after, before

I'm seeing the same thing for treefmt on 5d67ea6b4b63378b9c13be21e2ec9d1afc921713 of nixos-unstable

pre-commit-run> [WARNING] Unexpected key(s) present on local => treefmt: after, before

Ahh so these are definitely not keys that pre-commit is aware of.

And it looks like this bug was introduced because of the new ordering options merged earlier today.
#533

I assume the intent was not to have these options appear in the output JSON file but they certain are.
