Prepare and include demo of olmv1 commands in kubectl-operator plugin README

[azych]

Once we're done with extending kubectl-operator plugin with all the new olmv1 commands (and possibly deprecate olmv0 from there), we should prepare an asciicinema demo and include it in the kubectl-operator README, similar to how it's currently done for olmv0.

[joelanford]

We should also update the extension developer e2e to use kubectl operator rather than all of this:

operator-controller/test/extension-developer-e2e/extension_developer_test.go
