Upgrade librarian-puppet to version 1.3.2
Upgrade librarian-puppet to version 1.3.2

Upgrade librarian-puppet using:

```sh
bundle update librarian-puppet
```

Now that [we're using Puppet 3.6][puppet-3.6], we should be using
version 3 of the Puppet Forge API[1][2].

Upgrade libarian-puppet, which as of version 1.1.0[3] can support the
new API[4].

The change to actually start using the newer API is in the next commit.
