Addressing deprecated Pillow function usage in shavis

[StrixzIV]

Hi, when I'm running the shavis.py I've encounter some DeprecationWarning that raises from the script like this:

DeprecationWarning: NEAREST is deprecated and will be removed in Pillow 10 (2023-07-01). 
Use Resampling.NEAREST or Dither.NONE instead.

Upon investigating, I've discovered that your script are using Image.resize() function with the resampling mode of Image.NEAREST which will be deprecated in Pillow 10.

I'm forking and working on the problem now. Hope you like my solution!
