Default punctuation colour has changed

[linguini1]

Describe the bug
This plugin used to highlight punctuation in Gruvbox Orange, however it's been showing up as NeovimLightGray recently after I updated.

To Reproduce
Steps to reproduce the behavior:

1. Use Neovim version NVIM v0.10.0-dev-1809+g529498685b
2. Use the following setup:

return {
    "ellisonleao/gruvbox.nvim",
    priority = 1000,
    config = function()
        require("gruvbox").setup({
            contrast = "hard",
        })
        vim.cmd.colorscheme("gruvbox")
    end,
}

Expected behavior
Punctuation characters, such as {} and [] should show up as orange.

Screenshots
Here you can see that parenthesis and and commas show up in light gray. The curly braces are showing up as orange, but only because they're considered constructors. In C syntax, for example, they also show up as light gray.

Additional context
I have a hunch that this is due to Neovim recently changing the default color scheme. I'm thinking that maybe some of the highlight groups aren't getting overridden properly.

I can achieve the desired result with this config:

return {
    "ellisonleao/gruvbox.nvim",
    priority = 1000,
    config = function()
        require("gruvbox").setup({
            contrast = "hard",
            overrides = {
                ["@punctuation.bracket"] = { fg = "#fe8019" },
                ["@punctuation.delimiter"] = { fg = "#fe8019" },
                ["@punctuation.special"] = { fg = "#fe8019" },
            },
        })
        vim.cmd.colorscheme("gruvbox")
    end,
}

I also noticed this when I updated to the latest Neovim nightly. There's a related issue in Neovim #26378. Based on the Neovim developers' response, it seems that plugin maintainer should not depend on Vim's default highlight group.

I am also having the same issue. Anyone know How to fix it and point me in the right direction. I can open a pull request

@punctuation.bracket, @punctuation.delimiter and @punctuation.special link to the Delimiter highlight group. But Delimiter link was removed in commit e57dd85.

I added this to my config:
["Delimiter"] = { link = "GruvboxOrange" },

Maybe this can be merged. See also: #80

I tried the above with no luck. Also tried this:

(still no luck) happened after I updated to latest nightly
