plugin: visualise key presses within neovim window, useful for demos

[practicalli-johnny]

I have used screenkey for demos before and it can be useful to help people understand how I did something (without verbally describing all the key presses)

Having a screenkey tool within Neovim (and Emacs) saves setup and makes it easier to use.

https://github.com/NStefan002/screenkey.nvim looks a very good implementation to try out.

The default window for screenkey.nvim is in the same location as the whichkey menu, so I may need to tweak locations.

If this plugin is good, then consider packaging for the Astrocommunity.

Adding the plugin config to lua/plugins/user-practicalli.lua, in the Editor tools section

  {
    "NStefan002/screenkey.nvim",
    lazy = false,
    version = "*", -- or branch = "dev", to use the latest commit
    opts = {
      group_mappings = true,
    },
  },

In the AstroNvim/astrocore plugin overrides later in the user-practicalli.lua file I've added a key binding for normal mode

          ["<Leader>uk"] = { "<cmd>ShowkeysToggle<cr>", desc = "Toggle Screenkey" },

There is a bug in this plugin when used with whichkey, where duplicate keys for motions and anything key triggering the whichkey menu

I am using https://github.com/nvzone/showkeys plugin instead of screenkey.

Showkeys doent have the duplicate key showing and was very easy to reposition (example in config)

I'm testing out the following config in lua/plugins/user-practicalli.lua

  {
    "nvzone/showkeys",
    lazy = false,
    cmd = "ShowkeysToggle",
    opts = {
      excluded_modes = { "i", "t" }, -- skip insert and terminal
      position = "bottom-center",
      show_count = true,
      maxkeys = 5,
      timeout = 5,
    },
  },

In the AstroNvim/astrocore plugin overrides later in the user-practicalli.lua file I've added a key binding for normal mode

          ["<Leader>uk"] = { "<cmd>ShowkeysToggle<cr>", desc = "Toggle Showkeys" },
