[GitHub Scripts] Milestone Dates and Repo File (#4319)

* [GitHub Scripts] Milestone Dates and Repo File

The focus of these changes is to update the logic for end dates
assigned to milestones such that a milestone ends on the first Friday
of the associated month. In addition, the set of managed repositories
was added and a parameter allowing it to be used was added to each script.
