Update documentation for Windows install

[apraga]

Hi,

Installing natively on Windows is not hard ... but you need to know how to do it ! I encountered issues with treesitter and neorg. Here's the minimal steps to get it working

1. install scoop package manager
2. scoop install neovim mingw (folloming nvim treesitter advice
3. use lazyvim and the minimal configuration. Mine is below
4. Run TSInstallSync norg
5. Enjoy

Lazyvim actually install luarocks so you don't need to install it (contrary to the README).
If the documentation could be updated, that would be great. I can offer a PR if needed

My minimal config in ~/.config/nvim/lua/plugins/neorg.lua :

return {
  "nvim-neorg/neorg",
  lazy = false,
  version = "*",
  config = function()
    require("neorg").setup({
      load = {
        ["core.defaults"] = {},
        ["core.concealer"] = {},
        ["core.completion"] = {
          config = {
            engine = "nvim-cmp",
          },
        },
        ["core.dirman"] = {
          config = {
            workspaces = {
              notes = "~/notes",
            },
            default_workspace = "notes",
          },
        },
      },
    })

    vim.wo.foldlevel = 99
    vim.wo.conceallevel = 2
  end,
}```
