 workflow

- Running containers in ARC requires Kubernetes mode which needs additional configuration
- Jobs will now run directly on the runner pods (Ubuntu-based)

Subject: [PATCH 05/12] Switch workflows to use self-hosted runners

Update all workflows to use runs-on: [self-hosted] instead of runner groups.
This allows jobs to run on any available self-hosted runner across baker1,
baker2, baker4, and baker7 clusters.

Subject: [PATCH 10/12] fix: Change workflows to use 'Default' runner group
 instead of self-hosted label

The baker runners are registered in the 'Default' runner group, but
specifying 'runs-on: [self-hosted]' doesn't match runners in named
groups. Changing to 'runs-on: Default' allows GitHub Actions to
properly route jobs to the available runners in the Default group.

This fixes the issue where jobs were stuck in pending state because
they couldn't find matching runners.

Updated workflows:
- tests.yml: changes and test jobs
- maven-checks.yml: maven-checks and presto-coordinator-image jobs
- prestocpp-linux-build-and-unit-test.yml: all jobs
- prestocpp-format-and-header-check.yml
- prestissimo-worker-images-build.yml
- test-npm.yml
- test-runner-pickup.yml
