text: Title: Duplicated pokemon-species in evolution-trigger #1
  Body: Dear PokeAPI team,
  
  **https://pokeapi.co/api/v2/evolution-trigger/1/** contains Magnezone 4 times. At index 192, 262, 294 and 298.
  Some others like leafeon and glaceon do also exist more than once.
  Is it possible to reduce the linked species that every species appears only once?
