Script the process of switching from dynamic plugin wrappers in the RHDH container to using their equivalent plugins from reg.rh.io.

Script should suggest the latest plugin versions compatible with the current RHDH version.

Before:

  - package: ./dynamic-plugins/dist/backstage-plugin-catalog-backend-module-github-dynamic

Soon (dev preview):

- package: oci://quay.io/rhdh-plugin-catalog/backstage-plugin-catalog-backend-module-github:0.7.9!backstage-plugin-catalog-backend-module-github

Later (GA):

- package: oci://registry.redhat.io/rhdh/backstage-plugin-catalog-backend-module-github:0.7.9!backstage-plugin-catalog-backend-module-github

See doc example showing how to configure with OCI artifacts:

https://docs.redhat.com/en/documentation/red_hat_developer_hub/1.5/html-single/adoption_insights_in_red_hat_developer_hub/index#proc-install-adoption-insights_title-adoption-insights

It should also propose a way to get those OCI artifacts into the customer's airgap. See https://github.com/redhat-developer/rhdh-operator/blob/main/.rhdh/scripts/prepare-restricted-environment.sh
