🌱 Fix ginkgo warnings

[lentzi90]

What this PR does / why we need it:

We were using some deprecated ginkgo functionality. Namely running tests asynchronously and using a custom reporter.
This commit fixes those warnings by running the tests synchronously and
using the standard reporter.

Hi @lentzi90. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
