Release button

[didierofrivia]

This PR introduces a new workflow for crafting a release, following the pattern used in Authorino Operator. It makes it convenient to trigger the workflow manually without the need to go through the process of creating a branch and manually triggering the make targets, committing and tagging.

It includes the building of both OLM manifests and Helm Charts.
