Describe the bug

After uninstalling the helm release the secret gateway-validation-cert is not cleaned up

Steps to reproduce the bug

kubectl create ns gloo-system
helm install gloo glooe/gloo-ee --namespace gloo-system --version 1.10.15 --set-string license_key=$LICENSE_KEY_EDGE 

## Wait

helm uninstall gloo -n gloo-system

Now query the secrets:

kubectl get secrets -n gloo-system                                                                                                                        

NAME                       TYPE                                  DATA   AGE
certgen-token-8pj9s        kubernetes.io/service-account-token   3      5m46s
default-token-9hxt6        kubernetes.io/service-account-token   3      14m
gateway-validation-certs   kubernetes.io/tls  

Expected Behavior

Expected result: The gateway-validation-certs secret is cleaned up.

Additional Context

Actual result: It is not.

Why might this be important?

A client of ours reported that this is causing issues when the CA changes and the secret needs to be manually removed:

Error: Internal error occurred: failed calling webhook "gateway.gloo-system.svc": Post "[https://gateway.gloo-system.svc:443/validation?timeout=10s](https://gateway.gloo-system.svc/validation?timeout=10s)": x509: certificate signed by unknown authority

I see the same behavior on enterprise chart v1.14.6.
