J. Ryan Stinnett 02569fca4b Support CI for matching branches on forks
Currently, people with push access to the main Riot repos can push matching
branch names to Riot and the SDKs, and CI will test all the branches together.
This change allows contributors to access the same ability when submitting
several matching PRs from their fork of each repo.
