vulnerability-overflow e2e-test seems to be fragile

Ref. https://github.com/statnett/image-scanner-operator/actions/runs/3874906199/jobs/6606779952, and I have also seen the same error before.

It seems like the TestAssert timeout causes the step to get a lower timeout than the configured timeout in the TestSuite (they don't add up).

I think removing the TestAssert timeout will give the vulnerability-overflow step a bit more time.

I think we can conclude that this error is still present.

FYI logs from the failed run

events.imagescanner.log
failed.log
job.out.41.log
pods.watch.log

It seems like the job.out.41.log is clipped and is not valid json. This might explain the "unexpexted EOF" error in controller log (failed.log).
