add tip on minority focussed prize categories

Suggesting this tip here.

I've attended a hackathon where there was a prize like this. While very clearly working on a solo hack, I was constantly interrupted by complete strangers from other teams on the first day asking if I'd like to join them. Most of them admitted that the reason for asking was they wanted to be eligible for the prize. I felt pretty crappy about it, and another woman I met there also felt pretty disturbed by it.
