clusters/aaa: upgrade kubernetes-external-secrets to v8.1.2

[spiffxp]

This upgrades kubernetes-external-secrets on aaa to the latest version for:

• CVE fixes
• v1 of the ExternalSecret CRD

This needs to be manually deployed

This will unblock #2224

Migrating all secrets to ExternalSecrets ref: #2220

Deployed

$ git checkout upgrade-aaa-k-e-s && cd kubernetes-external-secrets
$ k --context=aaa apply -f .
serviceaccount/kubernetes-external-secrets configured
service/kubernetes-external-secrets-metrics created
deployment.apps/kubernetes-external-secrets configured
customresourcedefinition.apiextensions.k8s.io/externalsecrets.kubernetes-client.io configured
clusterrole.rbac.authorization.k8s.io/kubernetes-external-secrets configured
clusterrolebinding.rbac.authorization.k8s.io/kubernetes-external-secrets configured
clusterrolebinding.rbac.authorization.k8s.io/kubernetes-external-secrets-auth configured
$ k --context=aaa --namespace=kubernetes-external-secrets delete service/kubernetes-external-secrets
service "kubernetes-external-secrets" deleted

But I'm not seeing the triageparty-release external secret like I would expect?

$ k --context=aaa get externalsecrets -A
No resources found

Checked out #2224 and deploy the prow externalsecret to confirm it's working...

spiffxp@cloudshell:~/k8s.io/prow (kubernetes-public)$ k apply -f .
persistentvolumeclaim/ghproxy unchanged
deployment.apps/ghproxy configured
service/ghproxy unchanged
serviceaccount/ghproxy unchanged
externalsecret.kubernetes-client.io/k8s-infra-ci-robot-github-token created

Oh right, copy-paste on the service account

$ k --context=aaa get externalsecrets -A

OK, it's happy now

$ k --context=aaa get externalsecrets -A
NAMESPACE   NAME                              LAST SYNC   STATUS    AGE
prow        k8s-infra-ci-robot-github-token   3s          SUCCESS   3m35s

I'm going to leave this WIP until I can figure out what's up with triage-party

[spiffxp]

Removed [wip], everything in here has already been deployed. I was informed by @ameukam out of band that triage party is expected to not quite be working correctly.
