Let contributors know why tests are failing

[pdurbin]

Currently we show them a red x with no details of which tests failed.

This is because https://jenkins.dataverse.org is behind a firewall.

Probably we will try to build something public using GitHub Actions. Unfortunately, out of the box, GitHub Actions doesn't show details of failures to the public. (See https://github.com/gdcc/api-test-runner/actions/runs/6126277581 for example.) The hope is to publish a report somehow, as discussed at https://dataverse.zulipchat.com/#narrow/stream/379673-dev/topic/github.20test.20reports/near/385654854 . See progress by @poikilotherm at https://github.com/IQSS/dataverse/compare/9916-action-reports

The other day @donsizemore mentioned that when this server moves there's a chance we can open it up.
