prometheus-openldap-exporter: remove

2.3.0 is the final release, the repo is now archived.

Also I don't use it anymore for quite a while, so it didn't have a real
nixpkgs maintainer either.

Closes #338712

 - The `shadowstack` hardening flag has been added, though disabled by default.
 
+- `prometheus-openldap-exporter` was removed since it was unmaintained upstream and had no nixpkgs maintainers.
+
 - `restic` module now has an option for inhibiting system sleep while backups are running, defaulting to off (not inhibiting sleep), available as [`services.restic.backups.<name>.inhibitsSleep`](#opt-services.restic.backups._name_.inhibitsSleep).
 
 - Support for *runner registration tokens* has been [deprecated](https://gitlab.com/gitlab-org/gitlab/-/issues/380872)
