Neovim Version

Build type: Release
LuaJIT 2.1.1692716794

   system vimrc file: "$VIM/sysinit.vim"
  fall-back for $VIM: "/__w/neovim/neovim/build/nvim.AppDir/usr/share/nvim"

Run :checkhealth for more info```

### Steps to Reproduce

1. Follow warning on startup and move config to `config.extensions.which_key` from `config.which_key`.
2. Restart nvim

### Expected Behavior

No error on startup.

### Actual Behavior

I am getting the following error on startup:

Error detected while processing VimEnter Autocommands for "*":

Looks like the `which_key.lua` in `util` is still referring to the old config?

### Minimal Configuration to Reproduce

```lua
local root = vim.fn.fnamemodify('./.repro', ':p')

-- set stdpaths to use .repro
for _, name in ipairs({ 'config', 'data', 'state', 'cache' }) do
  vim.env[('XDG_%s_HOME'):format(name:upper())] = root .. '/' .. name
end

-- bootstrap lazy
local lazypath = root .. '/plugins/lazy.nvim'
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({
    'git',
    'clone',
    '--filter=blob:none',
    '--single-branch',
    'https://github.com/folke/lazy.nvim.git',
    lazypath,
  })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
  -- do not remove the colorscheme! it makes testing nicer
  'folke/tokyonight.nvim',
  {
    'mrjones2014/legendary.nvim',
    dependencies = {
      -- place your `vim.ui.select()` handler plugin here
      -- for example:
      -- 'nvim-telescope/telescope.nvim',
      -- 'stevearc/dressing.nvim',
    },
  },
  -- add any other pugins here
}

require('lazy').setup(plugins, {
  root = root .. '/plugins',
})

require('dressing').setup()

require('legendary').setup({
  -- add any options here
})

-- add anything else here
vim.opt.termguicolors = true
-- do not remove the colorscheme! it makes testing nicer
vim.cmd([[colorscheme tokyonight]])

Whoops, sorry about that. Thanks for testing new versions early! Does #405 fix it for you?

[mrjones2014]

Should be fixed in v2.13.3
