Z_RAISE_AFTER_PROBING value was being ignored by Marlin because

raise_z_after_probing() was only called if the printer type was set to a
DELTA or if the printer had a docking sled for the probe.

Marlin/Marlin_main.cpp

       // Sled assembly for Cartesian bots
       #if ENABLED(Z_PROBE_SLED)
         dock_sled(true); // dock the sled
+      #elif Z_RAISE_AFTER_PROBING > 0
+        raise_z_after_probing();
       #endif
 
     #endif // !DELTA
