azure_mgmt_resources deprecated and unsupported since 1 January 2022

This ruby project has a reference to the gem `azure_mgmt_resources`. This gem got unsupported per 1 January 2022.
As per the message on their repo https://github.com/Azure/azure-sdk-for-ruby:

> As of February 2021, Azure Resource Management SDK for Ruby has entered a retirement phase and is no longer officially supported by Microsoft. Here is the complete list of packages that are affected by this. We are committed to making critical security and bug fixes for libraries in this repo until December 31, 2021. After that date, this repo will no longer be maintained.

What would be a supported alternative?

The migration guide points to the gem `ms_rest_azure` but this seems to ge governed by the same deprecated github project.

No file or test is named. Start by locating the reference to the azure_mgmt_resources gem, then read the Azure Resource Management SDK retirement notice and migration guide linked in the issue. Done means replacing the unsupported dependency with a supported alternative and verifying the project still checks Azure access.
