Issue description

At some point since the last successful flake.lock update a change to nixpkgs seems to have changed how certain files in the TOML and YAML filetype gety generated.

This results in 4 test cases failing:

This mirrors home-manager-bots failed flake.lock update from today: CI link

The first nixpkgs that I tried was 7ffd9ae656aec493492b44d0ddfb28e79a1ea25 from my PRs own bump commit yesterday.

Any good way to show the differences between two nixpkgs revs? I only found commands that look like they require building two entire sets of nixpkgs first

[r-vdp]

This is only affecting the tests, right? The generated files are not invalid?

If so, I guess we just need to update the tests.

As far as I can tell, yes. It's also only removing superfluous blocks with no keys(e.g. font when only under font.bold are keys).
If none of the applications care about those this should be trivial.
