node-audit & node-outdated don't generate artifacts
## Description
(Describe the feature clearly and concisely.)
* Contrary to what is written in the documentation, the node-audit and node-outdated jobs do not generate an artifact. I cannot therefore retrieve the results to integrate them into vulnerability management tools (defect dojo).
## Implementation ideas
(If you have any implementation ideas, they can go here.)
(Any design change proposal could be also discussed on the _to be continuous_ Google Group: https://groups.google.com/g/tbc-dev.)
* Add artifact creation for node-audit & node-outdated jobs as present in yaml for node-build & node-lint jobs
