fix (extensions/tekton) : Remove knative duck classes from tekton tri…

…ggers model (fabric8io#5113)

+ Both tekton-triggers-v1beta1 and tekton-triggers-v1alpha1 seem to be
  generating knative duck types that result in split package warning when
  both packages are used together. Use these packages from common
  knative-model dependency rather than generating it.
