Demo for VTI

What's this?

A GitHub action running vti diagnostics on each commit to type-check your Vue project.

Output for latest commit on master:

Getting diagnostics from:  [ 'src/App.vue', 'src/components/HelloWorld.vue' ] 

File : /Users/pine/Code/workshop/vti-demo/src/App.vue
Error: Type '{ name: string; }' is missing the following properties from type 'String': charAt, charCodeAt, concat, indexOf, and 41 more.

File : /Users/pine/Code/workshop/vti-demo/src/components/HelloWorld.vue
Error: Property 'name' does not exist on type 'String'.

You can run yarn && yarn type-check to get these errors on CLI as well.

This PR fixes the type error and the build then passes.
