Concurrent E2E runs share the same headlamp-e2e release name in
privilegedescalation-dev. When two runs overlap, one run's teardown
(if: always()) deletes the shared Deployment/Service/ConfigMap while
the other is still using it, causing Playwright auth setup to time out
waiting for the Headlamp UI.
Adds a repo-wide concurrency group so only one E2E run executes at a
time. cancel-in-progress: false queues incoming runs rather than
cancelling in-flight ones to avoid leaving dangling cluster resources
when teardown is interrupted.
Fixes: PRI-815
