The `` MergeRequestDiffEntity#version_index when @merge_request_diffs.size > 1 returns difference between size and diff index ``
test matches one of the following conditions:
1. has either ~"flakiness::1" or ~"flakiness::2" label set, which means the number of reported failures
is at or above 95 percentile, indicating unusually high failure count.

2. has ~"severity::1" label set, which means the number of reported failures
[spiked and exceeded its daily threshold](https://gitlab.com/gitlab-org/ruby/gems/gitlab_quality-test_tooling/-/blob/c9bc10536b1f8d2d4a03c3e0b6099a40fe67ad26/lib/gitlab_quality/test_tooling/report/concerns/issue_reports.rb#L51).

This MR quarantines the test. This is a discussion starting point to let the
responsible group know about the flakiness so that they can take action:

- accept the merge request and schedule the associated issue to improve the test
- close the merge request in favor of another merge request to delete the test
