Support for nix-ts-mode

[terlar]

There is now a tree-sitter based Nix mode that behaves better in some sense, but I still see a bit of weird cases.

Anyways I tried to duplicate all the nix-mode definitions with nix-ts-mode and it kind of works, however, it seems on multi-line '' blocks the indentation is not stripped and you get an extra line first/last.

Editing:

{
  abc = {
    home = {
      home = {
        sessionVariables.DOCKER_HOST = "unix://$XDG_RUNTIME_DIR/podman/podman.sock";
        file.".actrc".text = ''
          --platform ubuntu-latest=catthehacker/ubuntu:act-latest
          --container-daemon-socket /run/user/${
            toString config.users.users.${config.abc.username}.uid
          }/podman/podman.sock
        '';
      };
    };
  };
}

Yields:

          --platform ubuntu-latest=catthehacker/ubuntu:act-latest
          --container-daemon-socket /run/user/${
            toString config.users.users.${config.abc.username}.uid
          }/podman/podman.sock
        

With nix-mode I get:

--platform ubuntu-latest=catthehacker/ubuntu:act-latest
--container-daemon-socket /run/user/${
  toString config.users.users.${config.abc.username}.uid
}/podman/podman.sock

Any ideas what could be the culprit?
