nixos/network-interfaces: remove network-interfaces.target

nixos/doc/manual/release-notes/rl-2405.section.md

···
 
 - `paperless`' `services.paperless.extraConfig` setting has been removed and converted to the freeform type and option named `services.paperless.settings`.
 
+- The legacy and long deprecated systemd target `network-interfaces.target` has been removed. Use `network.target` instead.
+
 - `mkosi` was updated to v19. Parts of the user interface have changed. Consult the
   [release notes](https://github.com/systemd/mkosi/releases/tag/v19) for a list of changes.
