Removed the increase_caught_count call inside of the 'update_pokedex_related_infos(pkmn)' method to prevent a double increase of the caught count

MR Description

• This MR removes the $pokedex.increase_creature_caught_count(pkmn.id) call from the def update_pokedex_related_infos(pkmn) method to prevent an extra increase of the caught_count
• Since the right place to call this method already exists in GameState def add_pokemon(pkmn) there are no extra changes needed

Tests to realize

• $pokedex.creature_caught_count(db_symbol of the pokemon you are testing with) = 0 or any other number
• After catching the pokemon where you checked the caught_count previously check it again the number should be the old number +1
