Re-evaluate shipping gatekeeper audit logs

https://repo1.dso.mil/platform-one/big-bang/apps/core/fluentbit/-/blob/5fdcd45009b0d7b572fa31936b7b478484089762/chart/values.yaml#L430

By default we exclude the gatekeeper audit logs from tailing. Since cluster auditor no longer ships to elasticsearch I think we need to revisit this policy and potentially remove the exclusion.
