Description

This adds an example of using group by function to achieve what is requested in #3647:

• Inherit Tags from Parent Task [when grouping by tag] - Documentation added #3647

Implementing the more general case requested in that issue would be a lot more work, so I've settled on documenting how to do the specific case requested.

Motivation and Context

Fixes #3647
