OTA-1813: Drop a local label on alert-risk e2e

This is to follow up [1].

We need to fire an alert to test the feature, but it would lead
to a job failure unless we get an exception from TRT via [2].

The local label exclusion in test configuration [3] are left
for the "local" cases in the future.
