The GitHub Actions runner may occasionally lose communication with the server (i.e. get denial-of-service'ed) when running twister directly on the runner host.
To work around this, run twister inside a container, which is isolated from the GitHub Actions runner pod, as does the Zephyr main CI twister workflow.
This commit also reworks the existing environment-specific steps for the CI Docker image environment.
