Currently we have 2 ways to rerun playwright jobs:

1. Open or push something to a PR
2. Click on the build-playwright-test job in Github and click "Rerun jobs" or "Rerun failed jobs"

We could add another way to rerun them by adding support to the playwright-actions.yml in the backend and frontent repos to trigger the build-playwright-test job by PR comment (similar to how we can trigger konflux jobs by commenting /retest on the PR)
