Switch E2E tests from GitHub-hosted runners to self-hosted k3s-animaniacs
runners which have network access to headlamp.animaniacs.farh.net.
Changes:
- runs-on: k3s-animaniacs (from ubuntu-latest)
- Re-enable E2E on push/PR events
- Uses ARC (Actions Runner Controller) self-hosted runners
Resolves DNS resolution failures (ERR_NAME_NOT_RESOLVED) by using
runners in the same network as the Headlamp test instance.
Runner config: kubernetes/base/arc-runners/helmrelease-arc-runner-set.yaml
