Archive vetting test results to unblock publish (Unity-Technologies#165)

Publishing currently fails ([example](https://yamato.prd.cds.internal.unity3d.com/jobs/212-Unity.Mathematics/tree/1.2.0%2520%28tag%29/.yamato%252Fupm-ci.yml%2523publish/3023395/job/pipeline)) due to not finding test results from the `upm-ci package test` run in `Validate Package Linux Minimal` job.

Likely this broke due to some refactoring in Unity-Technologies@d34adde or similar PR.

This PR adds archiving of these results, which should unblock the Publish job.
