Summary
The production version of openshift-serverless-clients`kn` contains the `kn-workflow` plugin inside the `kn` binary and no separate installation is needed. In the documentation under Installation of Serverless Logic plug-in, there is described a procedure for installing the plugin by downloading the binary from the community repository. This is valid for the community documentation, but in production, this could lead to having two versions of the `kn-workflow` plugin installed.
If you follow the guide, you will get different outputs for running `kn workflow --version` a `kn-workflow --version`.
Current `kn` 1.7.1 contains `kn workflow` v0.25.0, but documentation here mentions 0.26.0 prerequisites.
