JAX runs are not counted correctly

[HereThereBeDragons]

Jax has in the same workflow test and build jobs.

right now it seems like for tests also the build jobs are counted and the failure of the tests is propagated up to the build:

      "jax": {
        "build": {
          "status": "failure"
        },
        "test": {
          "success": 15,
          "failure": 15,
          "in_progress": 0,
          "cancelled": 0,
          "skipped": 0
        }
