fix: add backwards compatibility for Pods to Jobs for k8s <v1.27 [CM-461]

[corban-beaird]

Ticket

CM-461

Description

Older version of Kubernetes don't have the expected label (batch.kubernetes.io/job-name), instead they use job-name. https://kubernetes.io/docs/reference/labels-annotations-taints/#job-name

This PR adds a fallback to handle backwards compatibility in the event that version of k8s being used does not support the latest job label key.
