ArgoCD v1alpha1 depreciated with 1.10

[strangiato]

OpenShift GitOps 1.10 depreciated the v1alpha1 API and it should be updated to v1beta1.

When applying the current OpenShift GitOps instance you get the following warning:

Warning: ArgoCD v1alpha1 version is deprecated and will be converted to v1beta1 automatically. Moving forward, please use v1beta1 as the ArgoCD API version.
Warning: resource argocds/openshift-gitops is missing the kubectl.kubernetes.io/last-applied-configuration annotation which is required by oc apply. oc apply should only be used on resources created declaratively by either oc create --save-config or oc apply. The missing annotation will be patched automatically.
argocd.argoproj.io/openshift-gitops configured

The API version in the instance should be updated. Need to validate if anything else needs to change.

Based on this:

https://access.redhat.com/documentation/en-us/red_hat_openshift_gitops/1.10/html-single/release_notes/index#new-features-1-10-0_gitops-release-notes

I think that everything should be fine since we are already using spec.sso.dex instead of spec.dex.

@gnunn1 Do you know of anything else with this API change that we should be aware of?
