Add ability to redirect logfile output

For one of my workflows that uses the gitlab-registry.cern.ch/ci-tools/docker-builder/tools image the aarch64 build generates a lot more output and enough so that the job errors with

...
Job's log exceeded limit of 4194304 bytes.
Job execution will continue but no more output will be collected.

If a trigger is used then a script can't be used as well, and so there's no way for me to be able to bypass this with tee. Can an option be added to allow for redirecting the job output to a dedicated log file?
