Typescript: Readme missing note about different between Vue3's template and Vue2's template type checking

[TrungRueta]

Hi!

In plugin's readme for now we missing note about setup compact mode for project to merge type checking template.

For now, after setup plugin and volar (vscode ext). when write template tag + v-for, it force to put key on same template tag:

This because volar checking follow Vue3 guide. In Vue2 key must apply to all child tags of <template /> tag, not itself.

To avoid this issue in Volar's document they has compact mode:

Volar - setup vue 2

// tsconfig.json
{
  "compilerOptions": {
    ...
  },
  "vueCompilerOptions": {
    "experimentalCompatMode": 2
  },
}

Im has not experience to creating PR on git, what i can do is raise issue and count of you guys :) . Hope my info i usefull.

Thank for plugin!

Thanks for noting! I am happy to have it noted in the docs. Maybe it's good for you to start getting familiar with making PR and to have proper credit for it. 👍
