Added SWSH285, SWSH286 to swshp.json

Those cards are already in the api but not on GitHub. I added them as they are returned by the api, with the following differences:

• I added the artists
• Pikachu V evolves to Pikachu VMAX instead of Raichu
• Pikachu VMAX does not evolve instead of evolving to Raichu
