Create a pipeline to validate a released version of a Tekton project

[afrittoli]

We need a way to validate releases for various Tekton projects, and we should use a Tekton pipeline for that. Eventually we should be able to automatically trigger the pipeline as a post release job.

The aim is not to validate that the code that we just released works fine, since that is tested before the release as part of our CI, but rather to verify that the release artifacts were correctly generated. We had an issue in the past with .ko.yaml not being generated properly, which caused the wrong base image to be used when building the release.
