What
Bumps the base image of the k3d dind image.
Also refreshes the test matrix to currently supported Docker and k3s (Kubernetes) versions.
Why
I mainly looked at this because we use the k3d dind image as a base image for our controller e2e-tests image. The installed software seemed outdated and I also noticed reported vulnerabilities.
Fixes #1482
Implications
Hopefully none - except improving the user experience when using the dind image.
