Release 6000: Magerun2 updated to support Magento 2.3

In this release we will update the command-line tool magerun2 from 2.2.0 to 3.0.1. This new version will add support for Magento 2.3. The new Magento version was previously not yet supported. Note that this new version will also remove support for 2.0.x and for PHP 5.6. If you still depend on those versions you can manually install an older version from here in your app user space.
