Georges Basile Stavracas Neto 4927452b84 workspace-manager, x11-display: Default to a single row 
This seems to have been the default in the past, but was (accidentally?) modified
by 8adab0275.

For GNOME 40, we'll be returning to our root with horizontal workspaces, so instead
of overriding it in GNOME Shell side, change the default back to what it once was.
