Niels de Vos 73244ab07b ci: add script to detect latest Kubernetes patch release
By using this script, we can pass Kubernetes versions like v1.19 to the
CI jobs. The jobs are then responsible for detecting the a full release
version, including the '.patch' suffix.

Versions are passed as 1.19, releases have the 'v' prefix as in v1.19.1.
