Subject: [PATCH 1/2] chore(CI/CD): Enable only one run per PR (cancel
 previous)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add concurrency and group for all GitHub actions, the group name is composed:
- github.workflow — the workflow's name: field (e.g. "Lint", "Test and Code Coverage")
- github.ref — the full ref of the branch or tag that triggered the run
  (e.g. refs/heads/feat/my-feature, refs/pull/42/merge)

Actions cancelling prior runs on new push: check-codegen, kustomize-validation,
lint, test, test-gnmi, test-e2e, test-chart, reuse, size-label.
Both publish-image, publish-chart are kept running, since we do not want to stop
them in the middle of push step, which would leave partial state.
