muster release v5.43.6

Fixed

• The chart takes an affinity. values.schema.json declared affinity as an object with no properties allowed, so every affinity a deployment set, a pod anti-affinity spreading two replicas over nodes for one, failed the install with Additional property podAntiAffinity is not allowed. The key now accepts any affinity, like nodeSelector. (giantswarm/agent-platform#1080)
