Unable to build kubernetes objects from release manifest: error validating "" error validating data: [ValidationError(Certificate.spec): unknown field "keyAlgorithm" in io.cert-manager.v1.Certificate.spec

I want to deploy a Pulsar Cluster on Kubernetes with TLS enabled.
I have followed Pulsar documentation to do this: https://pulsar.apache.org/docs/en/helm-deploy/

I have in advance install cert-manager. It is running well:
```
kubectl get pods --namespace cert-manager
NAME READY STATUS RESTARTS AGE
cert-manager-76d44b459c-vd8kl 1/1 Running 0 25m
cert-manager-cainjector-9b679cc6-jxm4b 1/1 Running 0 25m
cert-manager-webhook-57c994b6b9-trbtw 1/1 Running 0 25m
```

I have also prepared the helm release
```
git clone https://github.com/apache/pulsar-helm-chart
cd pulsar-helm-chart
./scripts/pulsar/prepare_helm_release.sh -n pulsar -k pulsar-mini -c
```

But when I want to deploy Pulsar cluster using Helm with tls enabled:
```
helm repo add apache https://pulsar.apache.org/charts
helm repo update

helm install --set initialize=true --set namespace=pulsar --set certs.internal_issuer.enabled=true \
--set tls.enabled=true --set tls.proxy.enabled=true --set tls.broker.enabled=true --set tls.bookie.enabled=true \
--set tls.zookeeper.enabled=true --set tls.autorecovery.enabled=true --set tls.toolset.enabled=true pulsar-mini charts/pulsar
```
I have that error:
```
Error: INSTALLATION FAILED: unable to build kubernetes objects from release manifest: error validating "": error validating data: [ValidationError(Certificate.spec): unknown field "keyAlgorithm" in io.cert-manager.v1.Certificate.spec, ValidationError(Certificate.spec): unknown field "keyEncoding" in io.cert-manager.v1.Certificate.spec, ValidationError(Certificate.spec): unknown field "keySize" in io.cert-manager.v1.Certificate.spec, ValidationError(Certificate.spec): unknown field "organization" in io.cert-manager.v1.Certificate.spec]
```

Does anyone have a solution for this?

In the case I enabled TLS on all the cluster and not additionally on all components, the Pulsar Cluster is deployed but the proxy pod is not present anymore.

Start with the cloned pulsar-helm-chart and scripts/pulsar/prepare_helm_release.sh, then inspect the charts/pulsar TLS resources and their cert-manager API expectations. Re-run the shown Helm installation with the installed cert-manager and verify that the manifests validate and the proxy pod is created when TLS is enabled.
