Add new prospective organizers of a new chapter in Zagreb, Croatia

[cosimameyer]

The PR itself looks good but the built is failing. I’m not at a computer at the moment and couldn’t figure out what exactly was causing the issue. It looks like there’s an issue with a token and this problem has been occurring since (minimum) two weeks. I’m wondering if this PR may solve it - but @drmowinckels you probably have the best overview here?

@cosimameyer I dont know why the token isnt working. I'll go ahead and merge as the rest is fine.
