title: Can I write my own custom rule in eslint config?
body: <p>Is it possible to write custom rule in eslint config?
  My case is based on type 'any'. In eslint doc is rule &quot;@typescript-eslint/no-explicit-any&quot;, but it's too strong for me. I want to block assignment like this:</p>
  <p><code>const dontknow: any = ''; const name: string = dontknow;</code></p>
  <p>Is it possible to block this case?</p>
