See if there's a less-verbose way of invoking a lookup plugin from a collection

[artis3n]

According to the docs, you can use the collections keyword to import a collection into a playbook to then use roles or modules by their name, but plugins must be the absolute name.

This means to use this plugin you must call

lookup('artis3n.github_version.github_version', 'ansible/ansible')

which is much too verbose. Wait and see what it looks like in a week with Ansible 2.9's official release. In the worst case, at least change the name of the collection so it makes more sense. Maybe artis3n.plugins.github_version or artis3n.github.release_version.
