In the "Configuring the Azure Continuous Integration Pipeline"

section
the step to "Replace the default template with the below YAML snippet and substitute the below variables with relevant values" has sample code that uses Docker@1 instead of Docker@2.
While using Docker@1 worked when I tried it today, I believe Docker@2 is recommended now. Docker@2 is what is documented on docs.microsoft.com:
https://docs.microsoft.com/en-us/azure/devops/pipelines/tasks/build/docker?view=azure-devops
so it would be nice to update the documentation to use Docker@2 instead of Docker@1
