title: Exclude "@babel/plugin-transform-regenerator" from "metro-react-native-babel-preset"
body: <p>I am using <code>metro-react-native-babel-preset</code>, but I need to exclude <code>@babel/plugin-transform-regenerator</code>. I tried all sort of things, but nothing works. I suspect that the issue is that <code>metro-react-native-babel-preset</code> requires the plugin directly, like this:</p>
  <pre class="lang-js prettyprint-override"><code>///node_modules/metro-react-native-babel-preset/src/configs/main.js
  
            plugins: [
            ...defaultPluginsBeforeRegenerator,
            isHermes ? null : require(&quot;@babel/plugin-transform-regenerator&quot;),
            ...defaultPluginsAfterRegenerator
          ].filter(Boolean)
  </code></pre>
  <p>Is there any way to disable this plugin but keep using the metro preset??</p>
  <p>My current config looks like this:</p>
  <pre class="lang-js prettyprint-override"><code>const babelOptions = {presets: [['module:metro-react-native-babel-preset', {exclude: ['regenerator-transform']}]], 
  module.exports = require('babel-jest').createTransformer(babelOptions);
  </code></pre>
  <p>Thanks!</p>
