Add support for showing a popover for milestones in GFM
What does this MR do and why?
This MR adds support for rendering popover to provide more details of milestone on hover within rendered markdown. Good thing is that this doesn't require cache invalidation for rendered blobs as we're not making any change to Banzai filter for milestones, data was already present, we just added a popover using the available data!
