build(travis): fix GitHub rate limiting (obs-websocket-community-projects#157)

Without authentication, GitHub uses simple IP-based ratelimiting with an extremely low limit. This makes it effectively impossible to use on a CI platform such as Travis.

Authenticated requests get a far higher rate limit, and are not IP-based.
