Update snippets and templates about ocm-vscode-extension HOT 2 OPEN

To illustrate the goal of this task, note this self-explanatory warning from a random deploy process:

Warning: cluster.open-cluster-management.io/v1beta1 ManagedClusterSetBinding is deprecated;
use cluster.open-cluster-management.io/v1beta2 ManagedClusterSetBinding

To avoid this specific warning in deployment based on our snippets or templates, we need to:

1- Update the various templates, i.e. the Git Subscription template.

2- Add a new snippets here, i.e. :

{
	"managedclustersetbinding-v1beta1": {
            ...
	},
	"managedclustersetbinding-v1beta2": {
            ...
	}
}

In regards to the snippets, we should also decide whether or not we want to keep the old v1beta1 version.

I think this is the CRD for ManagedClustersetBinding.

To illustrate the second goal of this task, we can take a look at the Subscription CRD, we can see properties such as overrides, packageFilter, and packageOverrides which has little to no representation in our snippets.

This is just an example, other resource kinds has other missing properties that might be useful to users.
We can discuss different properties for different kinds and decide together which, if any, we want to include in our snippets.
