go-neb is unmaintained, look for an alternative

[jfly]

We use go-neb to forward prometheus alerts to matrix:

infra/build/pluto/prometheus/alertmanager.nix

Line 35 in 02eeb97

receiver = "go-neb";

The go-neb github repo was archived on Jun 28, 2023. The README says "matrix-hookshot is the spiritual successor to Go-NEB".

Have we investigated replacing go-neb with matrix-hookshot?

There's NixOS/nixpkgs#342663 that "tracks" this in nixpkgs. As mentioned here there's https://github.com/jaywink/matrix-alertmanager that's meant to be used specifically for having alertmanager alerts in Matrix. Since we're only using go-neb for alerts currently, I think matrix-alertmanager is better suited to this instead of Hookshot.

I'm personally using matrix-alertmanager in my infra and recently started maintaining the package in nixpkgs. I plan to write a NixOS module for it once I find some free time.

Opened NixOS/nixpkgs#378966 as a draft, will iterate on it in the coming days.
