Added pokemons 494-500

[Zaenaria]

Description

Added pokemon 494-500 so it could be at an even 500. Left the item ID, X,Y, and size blank as no pictures yet. Generation was also left blank as most other ones were blank as well.

Just thought it would be nice to have exactly 500 pokemon listed.

Motivation and Context

Not required but might be nice to advertise 500 pokemon instead of 493.

How Has This Been Tested?

Did not test with the rest of the code. Since it is in the json object the affect to the code should be nothing.

Screenshots (if appropriate):

Hi please add spritesheets for the pokemons to add merge the code. Else code starts throwing errors.
