Add action auto-scroll (#30057)

Browse Source 
Adds an auto-scroll/follow feature to running actions (fix #25186, fix
#28535).

When new log lines are appended and the bottom of the logs container
(`.action-view-right`) is visible at this time, the page automatically
scrolls down to the bottom of the logs.
