Depend on the patched version of kube-rs

[siegfriedweber]

Description

Depend on the patched version of kube-rs available at https://github.com/stackabletech/kube-rs, ensuring the operators automatically benefit from the fixes.

The patched version of kube-rs avoids that null entries are not added to enums, see stackabletech/kube-rs#1. These null entries currently prevent the CRD documentations from being rendered.
