CML kubernetes pod destruction - job still running

Hi this problem occurred after https://github.com/iterative/cml/issues/1330 was fixed. Somehow the runner is still running when the termination request is made. Can/should I set a "grace period" somewhere?

```
{"level":"info","message":"Unregistering runner cml-cml-runner-1x1f33ub-5fg9nhw1..."}
{"level":"info","message":"GET /repos/cml-test/cml-tutorial-1/actions/runners?per_page=100 - 200 in 105ms"}
{"level":"info","message":"DELETE /repos/cml-test/cml-tutorial-1/actions/runners/30 - 422 in 136ms"}
{"level":"warn","message":"\tCancelling shutdown: Bad request - Runner \"cml-cml-runner-1x1f33ub-5fg9nhw1\" is still running a job\""}
```
