Format check fails but `nix fmt` brings no changes.

Describe the bug

Hi!

Format check fails. But running the formatter doesn't modify anything. It's all formatted but check fails.

To Reproduce

Steps to reproduce the behavior:

nix fmt

Observe 0 files changed output.

Then run:

nix build .\#checks.x86_64-linux.treefmt

The build fails.

Expected behavior

The build doesn't fail or the formatter formats.

System information

This flake. That is:

treefmt-nix rev 8cd95da6c30852adb2a06c4b6bdacfe8b64a0, used with nixpkgs:

treefmt-nix = {
  url = "github:numtide/treefmt-nix";
  inputs.nixpkgs.follows = "nixpkgs";
};

I am also encountering this issue with treefmt v2.0.1, running via cachix/git-hooks.nix.
