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
pinging @NixOS/nix-formatting.
I guess my time has come as well...
With this commit, I'm not just dropping my maintainer entry, but I'm also
resigning from my duties as a board observer and NixCon project lead.
I also terminated my Summer of Nix contract today.
I'll also stop hosting the local NixOS meetup.
The only "project" I'll finish under the NixOS Foundation umbrella is
Google Summer of Code because the mentees aren't even remotely
responsible for why I'm leaving, and it would be unfair to leave them
hanging.
I'm grateful for all the things I was able to learn, for all the experiences
I could gather, and for all the friends I made along the way.
NixOS is what makes computers bearable for me, so I'll go and work on
some fork (*something something* you always meet twice in life).
