Forbid the `flaky-examples-check` job to fail
This is the step 2 of #32308 (moved).
Once we have a comprehensive list of all the currently RSpec flaky examples, we can forbid the flaky-examples-check
job to fail, which means that any MR that would introduce a new flaky spec would have a red pipeline, hence no new RSpec flaky example could be introduced in master
.
