update azure deploy job

• Given that helm charts are migrated from service repository level to helm-charts-azure repository, whenever azure_containerize_helm job fails for any reason ( intermittent runner machine failures, failing to push to OCI etc..,), azure_deploy falls back to devops/azure/chart to deploy outdated (not actively maintained) helm charts.
• This is causing issues in azure glab environment like 401 with entitlements, indexing issues etc.,

This MR proposes the following changes:

• Updated azure_containerize_helm job from allow_failure: true to break the pipeline upon failure.
• Remove azure_deploy fallback to devops/azure/chart in case of non availability of azure_containerize_helm job's artifacts
