Currently when we try to use build.sh when neither docker or podman is present, it throws error :
The build process requires docker or buildah/podman installed. Please install any of these and make sure these are executable
Terminating with error!

What happened:
When k3s is installed without docker or podman, and try to use danm plugin, it throws the error:
The build process requires docker or buildah/podman installed. Please install any of these and make sure these are executable
Terminating with error!

No error
How to reproduce it:
Install k3s and run build.sh from danm
