[ibm-telco] : /opt/assisted-service-ztp/default_ocp_versions.json: No such file or directory

As we found some issue with using older version of AI stable.17.03.2021-13.18 / v1.0.18.3, we tried installing latest AI (prepare-environment role). But stable/4.7 branch code fails because it could not find the file /opt/assisted-service-ztp/default_ocp_versions.json. Also checked in the assisted-service git repo and saw this file is removed.

Then we tried deploying the latest AI using the ZTP main branch (prepare-environment role), it again failed because of same issue ( it could not find the file `/opt/assisted-service-ztp/default_ocp_versions.json).

The main branch code also has a reference to the role (install-assisted-installer) which does not exists in the main branch.
As a work around we are using sonofspike onprem AI playbooks for bringing up latest AI.

Assisted installer also has evolved,the workflow changed to integrate with ACM. In order to continue using the older workflow, you need to pin the AI images to the good known versions that were in stable branch.
