fix: map mongo_version to correct mongo playbook in containerized san…

[srathod-apphelix]

Summary

Fixes containerized sandbox builds failing with ERROR! the playbook: 5.0.yml could not be found when edxapp_container_enabled=true and mongo_version=5.0.

Jira - GSRE-4246

Purpose

The CreateSandbox Jenkins job sets mongo_version to version strings like 5.0, 6.0, and 7.0. The containerized path in ansible-provision.sh was using that value directly as the playbook name (5.0.yml), while the actual playbooks are mongo_5_0.yml, mongo_6_0.yml, and mongo_7_0.yml. This change maps mongo_version to the correct playbook basename in the same block that sets MONGO_*_ENABLED flags.

Changes

• Set mongo_playbook to mongo_5_0, mongo_6_0, or mongo_7_0 based on the selected mongo_version in ansible-provision.sh.
• Update the containerized provisioning loop to use $mongo_playbook instead of $mongo_version when invoking ansible playbooks.

Pull request overview

This PR fixes containerized sandbox provisioning failures by mapping mongo_version values like 5.0/6.0/7.0 to the correct Ansible playbook basenames (mongo_5_0/mongo_6_0/mongo_7_0) so the containerized provisioning path no longer tries to run nonexistent playbooks like 5.0.yml.

Changes:

• Introduces mongo_playbook mapping based on mongo_version alongside the existing MONGO_*_ENABLED flag selection.
• Updates the containerized provisioning loop to invoke $mongo_playbook.yml rather than $mongo_version.yml.

• The containerized provisioning loop now depends on mongo_playbook, but if mongo_version is unset/unsupported, $mongo_playbook expands empty and Mongo setup will be skipped (or an exported mongo_playbook could be used unintentionally). Add an explicit guard so failures are fast and diagnosable.

      for playbook in redis $mongo_playbook; do
          run_ansible $playbook.yml -i "${deploy_host}," $extra_var_arg --user ubuntu
      done
