Tests failing due to Retry Later blank page

Due to Protected Paths Throttle, tests have been failing with a "Retry Later" blank page.

This is causing unnecessary noise on Slack channels where pipeline results are reported, besides providing false-negative results.

Here is an example of a failed pipeline https://gitlab.com/gitlab-org/gitlab-qa/-/jobs/318822811.

I have also noticed it when running tests locally.

We should disable throttling for test executions.
