fix(*) various kind cluster bringup bugs (#126)

* The hard-coded Kuma version was ancient, so stop hard-coding it and
  use the online installation script to default to installing the latest
  version.
* Fix the face condition waiting for Kubernetes deployments to succeed.
* Fix the Kuma GUI link and port forwarding.
* Upgrade to the latest version of Kind.

This fixes #124.
