hiera ssh_authorized_keys case Sensitivity

[eimyss]

In github example it shows that authorized keys are defined in yaml like this 'ssh_authorized_keys:'.

However Puppet always complained with message: "Error while evaluating a Resource Statement, Evaluation Error: Resource type not found: Ssh_authorized_keys".

Since I changed my common.yaml with "Ssh_authorized_keys" (first letter is case) everything worked.
I would gladly do a PR to change the example in Readme.md, if you want.

Since I am really new in Puppet, I dont know if its an actual bug.

Puppet version: 6.14.0
Module Version: (found in metadata.json): 1.0.11
