Add missing tags to []conditions which got reported by crd checker

Adds the task which got reported by the crd checker recently added
as a pre-commit validation.

Also syncs the validation of the conditon parameters with [1].

In a follow up, we should integrate the new ObservedGeneration for
a condition [1]. The observedGeneration represents the
.metadata.generation that the condition was set based upon.
