Silvan Mosberger 374e6bcc40 treewide: Format all Nix files
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.

Configuration for Alertmanager IRC Relay as a Nix attribute set.
For a reference, check out the
[example configuration](https://github.com/google/alertmanager-irc-relay#configuring-and-running-the-bot)
and the
[source code](https://github.com/google/alertmanager-irc-relay/blob/master/config.go).
Note: The webhook's URL MUST point to the IRC channel where the message
should be posted. For `#mychannel` from the example, this would be
`http://localhost:8080/mychannel`.
