Fixed typo for Z_PROBE_AND_ENDSTOP support in pins_RAMPS.h.

Confirmed Sanity checks are working.....

Marlin/pins_RAMPS_13.h

   #define FILWIDTH_PIN        5
 #endif
 
-#if defined(Z_PROBE_ANDENDSTOP)
+#if defined(Z_PROBE_AND_ENDSTOP)
   // Define a pin to use as the signal pin on Arduino for the Z_PROBE endstop.
  #define Z_PROBE_PIN 32
 #endif
