Dashboards API: v2alpha2 missing pieces (#108293)

* Dashboards API: v2alpha2 missing pieces

* Fix issue with dashboard client scope for alpha versions

As we now have 2 different alpha versions for v2 we need to store the
clients separately.

* Improve debuggability of provisioning export test

- Add a helper function to print the tree structure.
- Be explicit about the expected file names expected in each case.

* Update pkg/registry/apis/dashboard/mutate.go

* Update pkg/services/authz/zanzana/server/server.go

* Review

* go lint
