with-typescript-eslint-jest example doesn't detect format/lint issues

[weedgrease]

Hey y'all!

Just installed a brand new with-typescript-eslint-jest app with yarn create next-app and uncommitted the prettier extensions so my .eslintrc.json file looks like:

  "extends": [
    "eslint:recommended",
    "plugin:react/recommended",
    "plugin:@typescript-eslint/recommended",
    "prettier",
    "prettier/@typescript-eslint"
  ], 

Then I went into pages/index.tsx and added ;; to the end of the first import and then ran yarn run lint and eslint didn't detect any errors. I thought VS Code eslint plugin was being wacky but the CLI returning no errors makes me super confused. I've had the most frustrating time implementing ESLint and Prettier with my Next.js project so I thought this starter would work out of the box.
