Fail to run `init` in lazy.nvim

[xudyang1]

Describe the bug
The bug arose all in a sudden after updating lazy.nvim

To Reproduce
Steps to reproduce the behavior:

1. Install lazy.nvim plugin manager
2. Setup init.lua, lua/config/lazy.lua and lua/config/init.lua

-- ~/.config/nvim/lua/config/lazy.lua
local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
	vim.fn.system({
		"git",
		"clone",
		"--filter=blob:none",
		"https://github.com/folke/lazy.nvim.git",
		"--branch=stable", -- latest stable release
		lazypath,
	})
end
vim.opt.rtp:prepend(lazypath)

local options = {
  defaults = {
    lazy = true, -- should plugins be lazy-loaded?
    version = "*", -- enable this to try installing the latest stable versions of plugins
  },
  ui = { -- The border to use for the UI window. Accepts same border values as |nvim_open_win()|.
    border = "rounded"
  }
}
require("lazy").setup("plugins", options)

-- ~/.config/nvim/lua/config/init.lua
vim.g.mapleader = " "
require("config.lazy")

-- ~/.config/nvim/init.lua
require("config")

3. Set up gruvbox.nvim plugin

-- nvim/lua/plugins/gruvbox.lua
return {
  { 
    "ellisonleao/gruvbox.nvim", 
    priority = 1000 ,
    init = function()
      require("gruvbox").setup({
        undercurl = true,
        underline = true,
        bold = true,
        italic = {
          strings = false,
          comments = true,
          operators = false,
          folds = true,
        },
        strikethrough = true,
        invert_selection = false,
        invert_signs = false,
        invert_tabline = false,
        invert_intend_guides = false,
        inverse = true, -- invert background for search, diffs, statuslines and errors
        contrast = "", -- can be "hard", "soft" or empty string
        palette_overrides = {},
        overrides = {},
        dim_inactive = false,
        transparent_mode = true,
      })
      -- vim.o.background="dark" -- system default
      vim.cmd("colorscheme gruvbox")
    end
  }
}

4. Save and exit neovim
5. Open nvim
6. See error

Running :colorscheme gruvbox produced the following error:

Fixed by specifying plugin version to the latest commit.

Version 1.0.0 does not contain new italic config.
