Fix and update for the PHP version

[Pleskan]

I have encountered the following problems:

1. Incorrect owner of the /var/www directory
2. Drush doesn't work without prior composer install command
3. Update PHP version to 8.3, which is required for Drupal 11.x

Thanks! I will take a look at this soon, hopefully—I actually just upgraded my own Drupal VPS and had to make a few similar modifications, but in a different playbook.

I just tested this pull request and it works perfectly at first attempt. The Vagrant machine I used was config.vm.box = "ubuntu/jammy64" (geerlingguy/ubuntu2004 is too old for the ondrej PPA repo).
