Horde Server - Out of Date Image on GitHub

Sorry to interject, but I’m trying to build Horde myself from source via

RunUAT.bat BuildGraph -Script=Engine/Source/Programs/Horde/BuildHorde.xml -Target=“Build Horde Server Installer”

Seems to largely be working, but it doesn’t quite finish.

It dies here. I don’t have docker on my windows box, and when I look in the BuildHorde.xml, the Stage Horde Installer Dashboard seems to be a linux thing?

Is this necessary to build the windows installer?
