W18: Invalid character in group name error in older Neovim version

[dchang]

Hey, thanks for a great colorscheme. Recently updated my plugins and started getting W18: Invalid character in group name errors. I'm on Neovim 0.7.2 and found this is due the capture group names in 631e0aa where @ was added in a later version. My :h group-name:

Not sure if you want to update any documentation, maybe tag the previous working commit fc2e308, or have another solution so just reporting it for now. Using { 'rebelot/kanagawa.nvim', commit = 'fc2e308' } in packer config works for me.

Thanks for the suggestion, I've opened and pinned #79, hope that helps!
