basic-ts template is outdated and does not compile

[jacksturtevant]

After going through the initial flow and selecting basic-ts, and restarting the server, there are multiple errors:

• npm start does not work. The script points to ./lib/index.js which does not exist
• after fixing ^, the app still does not compile with:

import { Probot } from "probot";
^^^^^^

SyntaxError: Cannot use import statement outside a module```

I think the command npm run build is missing. (In readme and dockerfile).
