Longwave Rad Actuators Test Build 2

Test build for internal testing of a feature related to long wave radiation EMS actuators, including the follow-up work on #11621. This build will be deleted.

p.s. It appears GitHub has updated the release label options here to include a "None" option. Previously, there were two checkboxes for a pre-release and the latest release; however, the checkboxes behaved like radio buttons - i.e. either-or, instead of multi-choice. They now have gone to radio buttons for "None," "Pre-release," and "Latest," which is a cleaner interface, IMO. I'm deploying this with the "None" option to see whether that has any consequences.
