[OSD-22081] Remove no longer needed one-off job.

[bergmannf]

This was only needed to remove the infra-node tolerations from clusters that do not modify those themselves.

What type of PR is this?

Cleanup

What this PR does / why we need it?

We had to rollback adding tolerations for dns-default pods to run on infra nodes, as some customer were also setting those, leading to automations overwriting each other.

Right now it is documented (https://docs.openshift.com/dedicated/networking/dns-operator.html#nw-controlling-dns-pod-placement_dns-operator) so customers should be able to do this.

This job removed the tolerations from the whole fleet and is no longer needed, as it was rolled out already.
