nixos/grafana-agent: remove

As described in https://github.com/NixOS/nixpkgs/pull/394017,
grafana-agent does not build with Go 1.23 anymore, and Go 1.22 has been
removed.

grafana-agent has been deprecated by Grafana (in favour of Grafana
Alloy), and will be EOL on 2025-11-01, which would be part of the
upcoming 25.05 release.

Instead of leaving us with a broken package, drop it alltogether, and
add release notes.

- [testers.shellcheck](https://nixos.org/manual/nixpkgs/unstable/#tester-shellcheck) now warns when `name` is not provided.
The `name` argument will become mandatory in a future release.
- `grafana-agent` and `services.grafana-agent` have been removed in favor of
Grafana Alloy (`grafana-alloy` and `services.alloy`), as they depend on an EOL compiler version
and will become EOL during the 25.05 lifecycle.
Grafana recommends migrating to `grafana-alloy` (`services.alloy`).
See https://grafana.com/docs/alloy/latest/set-up/migrate/ for details.
- `xdragon` package has been renamed to `dragon-drop`.
`xdragon` is an alias to `dragon-drop` and the package still provides `bin/xdragon`.
`bin/dragon` is no longer supplied.
