Description

Our automation for cleaning up test environments is failing consistently due to a change in azure cli extensions.

Describe the bug
Since yesterday afternoon workflow runs for Clean Validation Environments workflow have been failing with the following error:

WARNING: The 'cdn' and 'afd' command groups have moved to the 'cdn' CLI extension. Install the latest version with: az extension add --name cdn. The built-in cdn/afd commands in azure-cli core will be removed in a future release.
WARNING: Preview version of extension is disabled by default for extension installation, enabled for modules without stable versions. 
WARNING: Please run 'az config set extension.dynamic_install_allow_preview=true or false' to config it specifically. 
WARNING: The command requires the extension azure-firewall. It will be installed first.
ERROR: The checksum of the extension does not match the expected value. Use --debug for more information.

Steps to reproduce

  1. Run Clean Validation Environments or let it run as per the cron in the configuration.
  2. Observe the error outlined above.
