Update the azure-piprlines

The following images are deprecated in GitHub actions and Azure DevOps:

* `ubuntu-18.04` : actions/runner-images#6002
* `macos-10.15` : actions/runner-images#5583

Due to this there was failing tests due to planned brownouts.

Updated ubuntu18 to ubuntu22
Updated macos-1015 to macos12
