fix(ci): Use actions-runner base image and drop Volta from Dockerfile

Extend ghcr.io/actions/actions-runner:2.333.1 instead of plain ubuntu.
Remove Volta — actions/setup-node in workflow steps handles Node/Yarn.
Update HOME env to /home/runner to match the runner user in the image.
Remove enableCrossOsArchive since the container OS matches the host.
