Add resource import examples to documentation

[bcdady]

I am excited to see that OpenVPN is iterating on this provider.

As we begin to bring our OpenVPN configuration under management via Terraform code, it would be constructive to have examples of the proper syntax to import each resource.

Hello,
After checking we noticed that some resources have "Import" section in documentation, like this: https://registry.terraform.io/providers/OpenVPN/cloudconnexa/latest/docs/resources/user#import
And we found out that some resources missing "Import" sections. We created internal ticket to get this fixed (for reference: CAPI-401).

Just to verify, am i right that you was referring to this aspect? Or there is something else that you want to see (other that what mentioned above)?
