bug: swayosd doesn't have swayosd-libinput-backend.service

[bigbabyboost]

Are you following the right branch?

• My Nixpkgs and Home Manager versions are in sync

Is there an existing issue for this?

• I have searched the existing issues

Issue description

Based on the swayosd documentation, swayosd-libinput-backend can be enabled with systemctl enable --now swayosd-libinput-backend. However, NixOS does not include this service, even though the service is present in /nix/store/xxxxswayosd/lib/systemd/system/swayosd-libinput-backend.service. I’m wondering how to enable it?
