gha: release: Update the workflow

The release workflow is now updated to be a `workflow_call`, and it
includes the steps that had to be manually done in the past, such as
updating the needed files and creating the release itself.

While on this, the kata-deploy multiarch manifest tags have been updated
to match the new release scheme.
