Add missing information to CSV

[grzpiotrowski]

This PR attempts to fix #162.

It looks like adding the information to the CSV template sorts out the issue of missing names/descriptions.

There is one peculiar thing caused by two versions of AuthConfig CRD which results in two seemingly duplicated cards rendered in OperatorHub.

While the displayed name could be altered so the first card would display for example AuthConfig/v1beta1 and the second card AuthConfig/v1beta2 the YAML example displayed on both cards would still show an example from AuthConfig/v1beta2 (even for v1beta1 card), despite examples existing for both versions in the CSV file. It's a bit confusing, I hope this describes the issue in an understandable way.

For this reason I have included the example YAML for AuthConfig/v1beta2 only and kept the displayName for both versions as AuthConfig. This way the OperatorHub will only show the most recent version to the visitors with a correct YAML example.

As an example, this approach can be also seen in ArgoCD operator with the Argo CD schema.

To verify the changes, copy the full contents of the generated CSV manifest to OperatorHub Preview tool.

Also a pic of how it looks like after the changes:
