z-offset menu- better probe

I changed this line
this gcode.process_subcommands_now_P(PSTR("G28 Z"));
in this gcode.process_subcommands_now_P(PSTR("G28 Z\nG91\nG0 X-46 Y-8\nG90"));
in normal and in live adjust so the nozzle matches exactly the point where bltouch does the probe
the file is on
Marlin-Ender_3_V2_Extensible_UI\Marlin\src\lcd\extui\lib\creality_dwin\creality_dwin.cpp

I hope it's possible do it automatically, i don't know how do it
for me work very well
