puppet_server provisioner fails with Puppet Collection 1 with the
following error:
```bash
==> default: Running provisioner: puppet_server...
The `puppet` binary appears not to be in the PATH of the guest. This
could be because the PATH is not properly setup or perhaps Puppet is not
installed on this guest. Puppet provisioning can not continue without
Puppet properly installed.
