title: Method to make themes in vscode conditional
body: <p>I use bracket pair colorizer. Is it possible that the bracket pair settings can be modified if the theme is (for example) monokai?
  Ik its a json file and json files dont accept if statements, otherwise id write:</p>
  <pre><code>if &quot;theme&quot; == &quot;monokai&quot; {
    bracket-pair-colorizer-2.colors: [
      &quot;red&quot;,
      &quot;green&quot;,
      &quot;blue&quot;
    ]
  }, else {...}
  </code></pre>
  <p>Is there any way to make this reality?</p>
  <p>Edit:
  I tried setting <code>editor.tokenColorCustomizations</code>'s <code>brackets</code> option to a list, and string, then tried that with <code>parenthesis</code>, and <code>bracket</code>, but it simply said that it cannot do that</p>
