pip install commands for all Azure ML packages

This page shows only "pip install azureml-core" and lacks pip install commands for other Azure ML packages.

It'd be more user friendly to list all Azure ML packages with corresponding pip install commands on this page.

For my use case, I needed to spend some time figuring out required Azure ML packages for Azure ML Pipelines and pip install commands.
