Fix missing len function

[anthonysomerset]

Pull Request (PR) description

640078c brought in additional logic but seems to reference a non-existent function len

assuming this should actually be the core function length so updating to reference this

i am unsure if this is the desired output but my nodes are all working just fine with this change now

also updated the metadata to reference the correct https://github.com/voxpupuli/puppet-patching_as_code repo - as the forge page currently takes users to a non-existent repo url at present

This Pull Request (PR) fixes the following issues

Let me see if I can get the modulesync in #125 merged so that we can make a release.
