[Bug]: Changing chart values for cleanup seed files background job doesn't updated cronjob

[tw4l]

Browsertrix Version

v1.9.4

What did you expect to happen? What happened instead?

If I update cleanup_job_cron_schedule in my local Helm chart, I expect the existing cronjob that periodically cleans up unused seed files to have its schedule updated accordingly. Currently, this doesn't happen so you have to delete the existing cronjob and then re-deploy to update the schedule.

Reproduction instructions

1. Deploy Browsertrix
2. Set a new schedule for the seed file cleanup cron job in a local.yaml - e.g. cleanup_job_cron_schedule: "* * * * *"
3. Verify schedule isn't updated with kubectl get cronjobs
