(Follow up): Integrate Kapp: Add support for registryV1 bundles

[varshaprasad96]

#625 currently supports installation of only plain bundles - where all the manifests are present in a single location. This issue tracks the work required to support registryV1 bundles.

The YTT logic needs to be specified in the templating section of the App CR. The conversion logic to so is present here: https://github.com/varshaprasad96/ytt-olmv1-conversion/blob/main/annotations.yaml.

An example of a App CR installing a registryV1 prometheus bundle is available here: https://github.com/varshaprasad96/kustomize-olm-plugin/blob/main/app_tests_yamls/app_test.yaml.
