[5.2] Fix pokemon plural form

[scrubmx]

As with the words deer and sheep, the singular and plural forms of the word "Pokémon" do not differ, nor does each individual species name; in short, it is grammatically correct to say both "one Pokémon" and "many Pokémon"

But should we force the acute accent? 😀
