Added "s" to the end of Talents in the Swedish sheet

[Martin-Joensson]

Should be just, "Mutanttalang"

I’ll fix the translation. Thanks for reporting it.

Even though removing the "s" would make it better on the swedish character sheets they are just called "Talanger" excluding Mechatron where it's "Sekundärfunktioner". Don't know if the goal is to reflect the character sheet?

I've added more translation keys for the plurals version of talents. I am not speaking Swedish so I recommend to go through the se.json and check things out. The best way is to make changes and then create a Pull Request
