Stream `npm ci` output to log

What does this MR do?

When npm ci --production gets stuck a job timeout kills the job before the output from the command can be written to the logs. This change streams the output from stdout/stderr to the logger so that we can identify bottlenecks sooner without losing context due to jobs timeouts.
