Update Readme with Vetur information (#559)

* Update "Why doesn't it work on .vue file?"

I had an issue where the plugin works, but red markings of errors remained. So I found out the instructions for this section are missing a note regarding Vetur. You need the following setting to complete the setup:
```
"vetur.validation.template": false
```

Note:
While it solved my issue, there is something to consider with how it's applied. Eslint is mostly used in a per-project manner. This means, if you apply the rule above to `settings.json`, it is global a rule and Vue projects that do not use this plugin will not show template errors. So to solve this, you need to apply the setting locally. In the context of VS Code, it's easy. You just save a "workspace" to your project root and that creates a file, where you can apply the settings, thus locally. See [here](https://github.com/Microsoft/vscode/issues/37519) for details.

* Update README.md
