Do not run E2E jobs in predictive RSpec pipelines
Context
Goal
Ensures we don't run E2E tests on Predictive RSpec pipelines.
Those pipelines are meant to be really fast, as they run only the minimal amount of RSpec tests. Their P80 is currently around 75 minutes because we run E2E tests in them (e.g. 1, 2, 3).
