title: Change squiggly line color under warnings in VSCode
body: <p>After installing ESLint in VSCode, I'm receiving some warnings like:</p>
  
  <blockquote>
    <p>'variable' is assigned a value but never used</p>
  </blockquote>
  
  <p>The underline color is red, but how do I change that color? I have tried:</p>
  
  <pre><code>"workbench.colorCustomizations": {
      "editorWarning.foreground": "#00FF00",
      "editorError.foreground": "#00FF00",
      "editorWarning.border": "#00FF00",
      "editorError.border": "#00FF00"
  }
  </code></pre>
  
  <p>but they change the color of the underlined border, which is not the squiggly one as shown here:</p>

  <p>How do I change that red color into <code>#00FF00</code> instead?</p>
