Fix case-sensitive value for driftDetection ignore

General MR

Summary

fix case-sensitive value for driftDetection ignore.

This fixes the issue where the CronJob threw a driftDetection warning/correction after firing.

Prior to the fix, manually editing the CronJob/neuvector-cert-upgrader-pod would cause the warning and the CronJob would get reverted -- CronJob should be ignored per our overrides...but the kind: value is case-sensitive.

With this fix, the CronJob/neuvector-cert-upgrader-pod update is ignored as expected, and no warning is thrown.
