title: ts-jest Optional Chaining not working if tsConfig Target as ESNext, ES2021 or ES2020
body: <p><strong>Optional Chaining</strong> is creating issue when I'm try to set the tsConfig Target as ESNext, ES2021 or ES2020.
  But works fine when I set the target to <strong>ES2019</strong>.
  Not sure what I am doing wrong.</p>
  <p>Below is the look alike of my jest config:</p>
  <pre><code>{
      ...,
      transform: {
          '^.+\\.(ts|tsx)$': 'ts-jest',
      },
      globals: {
          'ts-jest': {
          tsConfig: {
              target: 'ES2019',
          },
      },
  }
  </code></pre>
