Format all Nix files using the officially approved formatter,
making the CI check introduced in the previous commit succeed:
nix-build ci -A fmt.check
This is the next step of the of the [implementation](https://github.com/NixOS/nixfmt/issues/153)
of the accepted [RFC 166](https://github.com/NixOS/rfcs/pull/166).
This commit will lead to merge conflicts for a number of PRs,
up to an estimated ~1100 (~33%) among the PRs with activity in the past 2
months, but that should be lower than what it would be without the previous
[partial treewide format](https://github.com/NixOS/nixpkgs/pull/322537).
Merge conflicts caused by this commit can now automatically be resolved while rebasing using the
[auto-rebase script](8616af08d9/maintainers/scripts/auto-rebase).
If you run into any problems regarding any of this, please reach out to the
[formatting team](https://nixos.org/community/teams/formatting/) by

Due to how complex minecraft world generation has gotten in recent
years, it now can take several minutes to complete the first generation
of a world seed, even on relatively new and powerful hardware.
We are testing if a minecraft server can run inside of a nix enviroment,
and not so much about stress testing the CI.
Test running before this change:
> (finished: waiting for TCP port 43000, in 118.49 seconds)
Test running with this change:
> (finished: waiting for TCP port 43000, in 27.88 seconds)
Choice of using `level-type` and `generate-structures` was made as they
support almost every version of minecraft. These two also make it
extremely clear what it does, compared to the more complex
`generator-settings` and all its toggles.
