title: "TSLint still there" => upgrading from TSlint to ESLint
body: <p>I'm working on angular 10 project, which was upgraded to angular 12. TSLint is no longer used in angular 12, but since that project was upgraded to angular 12, it still has <code>tslint.json</code> and its packages. How do I remove it? The project uses prettier as well.</p>
