title: Package doctrine/reflection is abandoned
body: <p>I get this warning when I  run <code>composer update</code> :</p>
  <blockquote>
  <p>Package doctrine/reflection is abandoned, you should avoid using it. Use roave/better-reflection instead.</p>
  </blockquote>
  <p>I tried to add roave/better-reflection instead and remove doctrine/reflection without success.
  I'm on Symfony 5.2 but I already had the warning with Symfony 5.1.</p>
  <p>Thank you in advance.</p>
