docs(language-service): update neovim lsp set up info

[CofCat456]

The tutorial for setting up Volar 2.0 on NeoVim has been updated.

The use of multiple servers is no longer applicable in the new version.

To help users who are updating Volar on Neovim quickly find the correct configuration, issue #3925 serve as the new link.

Can we outline exactly what is needed here. That link there are a lot of trial and error comments. And using 2.0.7 is still not working for me. ( so I am still sitting pretty @ v 1.8.27 )

I have tried adding to tsserver

local lspconfig = require "lspconfig"

local vue_ts_plugin_path = require('mason-registry')
           .get_package('vue-language-server'):get_install_path() .. '/typescript-plugin'

lspconfig.tsserver.setup {
  init_options = {
    plugins = {
      {
        name = '@vue/typescript-plugin',
        location = vue_ts_plugin_path,
        languages = { 'vue' },
      },
    },
  },
  capabilities = capabilities,
  filetypes = { "typescript", "typescriptreact", "vue", "json" },
}

This is after following this RayGuo-ergou Dotfiles

Thank you! 😃
