~~It looks like Git Push is taking more than 10 seconds at which point the test times out.~~

The test actually fails after waiting for 10 seconds for the /api/v4/projects/:project_id_or_path/events?action=pushed API to show the push event.

This is intermittent. The test passes on retry: https://ops.gitlab.net/gitlab-org/quality/staging/-/jobs/802885
