[Bug] Helm3 cli pulls v2 helm chart version in 0.19.0

Strimzi helm repo contains two versions of helm chart release for 0.19.0, one for helm 2 and other for helm 3. However, there is no way to get helm v3 client working with v3 chart .

This cause errors in installing/updating operator using helm3 clients when CRDs are previously installed

To Reproduce

$ helm version
version.BuildInfo{Version:"v3.2.4", GitCommit:"0ad800ef43d3b826f31a5ad8dfbb4fe05d143688", GitTreeState:"clean", GoVersion:"go1.13.12"}

$ helm repo add strimzi https://strimzi.io/charts/ 
"strimzi" has been added to your repositories

$ helm repo update
Hang tight while we grab the latest from your chart repositories...
...Successfully got an update from the "strimzi" chart repository
...Successfully got an update from the "stable" chart repository
Update Complete. ⎈ Happy Helming!⎈ 

$ helm install --debug  --dry-run test  strimzi/strimzi-kafka-operator
install.go:159: [debug] Original chart version: ""
install.go:176: [debug] CHART PATH: xxx.cache/helm/repository/strimzi-kafka-operator-helm-2-chart-0.19.0.tgz

Error: rendered manifests contain a resource that already exists...

Expected behavior

$ helm install --debug  --dry-run test  strimzi/strimzi-kafka-operator
install.go:159: [debug] Original chart version: ""
install.go:176: [debug] CHART PATH: xxx.cache/helm/repository/strimzi-kafka-operator-helm-3-chart-0.19.0.tgz

and no errors

@klalafaryan As we are slowly deprecating Helm v2 (which is being deprecated anyway), I will not add it to the index file anymore in 0.20.0 release (zip file will be still there for download) and I expect it to be removed after the release.

Link is easy … it is in the GitHub release, at the bottom: https://github.com/strimzi/strimzi-kafka-operator/releases/tag/0.19.0
