Description

The oxocarbon dark transparent theme crashes NVF:

Reproduction steps

My nvf config: https://codeberg.org/Axe/NixOS-Config/src/branch/master/home/nvf.nix Minimal config:

{
  programs.nvf = {
    enable = true;
    settings = {
      vim = {
        theme = {
          enable = true;
          name = "oxocarbon";
          style = "dark";
          transparent = true;
        };
      };
    };
  };
}

Expected behavior

Starting nvim should load NVF with the oxocarbon theme and a transparent background

Actual Behavior

Error detected while processing VIMINIT..script /nix/store/9108xgifl452m7iaysr02sdf3mq3kmx2-mnw-configDir/init.lua:
E5113: Error while calling lua chunk: ...k/mnw/start/indent-blankline-nvim/lua/ibl/highlights.lua:95: No highlight group 'IblScope' found

        .../9108xgifl452m7iaysr02sdf3mq3kmx2-mnw-configDir/init.lua:5: in main chunk
Press ENTER or type command to continue

It then gives an unthemed neovim

I believe this is a bug in the indent-blankline plugin that occurs when it is enabled simultaneously with Oxocarbon. I am not entirely sure if we can actually fix this, but I'll bump both plugins and see if it helps.
