Use Schedule Pipeline description instead of last branch commit comment

Problem to solve

Currently when running scheduled pipelines, the last commit message is displayed. Scheduled pipelines run on a specific branch with listed variables. There may be 1 to N schedules for each branch. It would be easier to determine which schedule was ran if the description was displayed instead of the last commit message.

Intended users

Developers, administrators, and managers looking at reports would find it easier to determine which schedule was ran if they could see the description when viewing pipeline results.

User experience goal

The user should be able to quickly determine the schedule pipeline that was ran.
