DEV: Flaky test report should be differentiated between job runs (#24895)

Why this change?

The `tests` workflow runs many jobs. Each job when ran is given a unique
id. Since a job can be re-run, we do not want the test reports to
override each other so we differentiate it further by the `job_id` given
by `${{ github.job }}`.
