Automate Release Process

This should be simple. trigger off version tag and release. MVP is release of kuttl.. but would love to automate:
1. kuttl release
2. docker release
3. krew update (this is the more challenging component as it requires a PR to that repo)

likely want to use github actions... should look at moving to actions for all CI

**What would you like to be added**:

**Why is this needed**:

The issue proposes GitHub Actions automation triggered by a version tag, initially for the kuttl release, with Docker and Krew updates also considered. Start by checking the repository's existing CI and release configuration; done means the tagged-release workflow and the scope of Docker and Krew automation are explicitly resolved.
