Config file syntax highlight in neovim

[zhengpd]

I did nvim ~/.config/ghostty/config and the buffer is not syntax-highlighted. The reason is that lazy.nvim resets rtp by default. My solution is to add Ghostty nvim plugin to rtp:

{
  performance = {
    rtp = {
      paths = {
        "/Applications/Ghostty.app/Contents/Resources/nvim/site"
      },
    },
  },
}

I didn't find any issue talking about the syntax highlight problem so I'm sharing it here.
