D9 - Drupal init fails generating automplete files. The Class 'Symfony\Component\Process\ProcessBuilder' is not available anymore in Symfony 4.4

Similar issue: https://github.com/pact-foundation/pact-php/pull/61/commits/085d7bf5adf402201782d1cc1303ccd163f2cfeb

Fixed by using intead: use Symfony\Component\Process\Process;

I encountered this issue with ProcessBuilder being unavailable when attempting to use Alchemy/Zippy.

The latest release of Alchemy/Zippy (0.4.9) — which Drupal Console currently installs as a dependency — still uses ProcessBuilder.

You can see that amongst the commits to master since 0.4.9, they've updated Zippy to use Process instead of ProcessBuilder, but have yet to make it part of an official release.

The ProcessBuilder class was removed from symfony/process in the 4.0.0 release: CHANGELOG.md
