It looks like after the change to use the setup-maven action in the workflow ([link](https://github.com/openjdk/jmc/blob/master/.github/workflows/validate.yml#L87)) we cannot run CI in our forks.

@aptmac : even after referencing the issue. it still does not appear to run the ci tests on the pr. Any way to trigger it? As the pr is speculative, it does not make sense to merge it before we have tested it.
