puppetlabs/stdlib dependency appears to be 4.20.0 and not 4.13.1

[tullis]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 4.10 PC1
• Ruby: 2.1.5p273 [x86_64-linux-gnu]
• Distribution: Debian
• Module version: 4.1.0

How to reproduce (e.g Puppet code you use)

Run puppet agent with version 4.13.1 of stdlib specified in Puppetfile

What are you seeing

Manifest failure with error:

Error: Unknown function: 'to_yaml'. at /etc/puppetlabs/code/environments/prometheus/third_party/prometheus/manifests/alerts.pp:35:30

What behaviour did you expect instead

Manifest compilation.

Output log

Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Resource Statement, Evaluation Error: Unknown function: 'to_yaml'. at /etc/puppetlabs/code/environments/prometheus/third_party/prometheus/manifests/alerts.pp:35:30 on node test
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run

Any additional information you'd like to impart

Updated to version 4.20.0 of stdlib and the manifest compiled.

I checked the changelog of stdlib and the to_yaml function appears to have been introduced in version 4.20.0
