bug: Remapped registers key doesn't trigger which-key

Did you check docs and existing issues?

• [X] I have read all the which-key.nvim docs
• [X] I have searched the existing issues of which-key.nvim
• [X] I have searched the existing issues of plugins related to this issue

Neovim version (nvim -v)

Describe the bug

I've remapped my registers key to ', and I can't get which-key to trigger when pressing it.

I've already looked at #483, where the following was suggested:

{
  'folke/which-key.nvim',
  config = function()
    local actions = require("which-key.plugins.registers").actions
    table.insert(actions, { ... }) -- Add remapped triggers here
    require("which-key").setup()
  end,
}

This does not do anything for me. I've included this as a step in the reproduction below.

Steps To Reproduce

1. Remap the registers key

vim.keymap.set({ "n", "v" }, "'", "\"")

2. Apply the fix suggested in #483

{
  "folke/which-key.nvim",
  config = function(_, opts)
    -- Show registers when pressing remapped ' key
    local registers_actions = require("which-key.plugins.registers").actions
    table.insert(registers_actions, { trigger = "'", mode = "n" })
    table.insert(registers_actions, { trigger = "'", mode = "v" })
    require("which-key").setup()
  end,
},

3. Press '

Expected Behavior

The registers which-key window should show, but nothing happens. The window still shows when pressing ".

You can try it like that, but it is not possible to remap the character "\"" to "'".

    keys = {
      { "'", "\"", desc = "keyremap", mode = { "n", "v" }, remap = true },}

Not stale, still relevant

I can still not get this to work, neither by just remapping nor by applying the following fix:

local registers_mappings = require("which-key.plugins.registers").mappings
table.insert(registers_mappings, { "'", mode = { "n", "x" }, desc = "registers" })

Am I missing something here?
