You should change your appstore name to "Worqshop, a github client for iPhone" then you will show up in iOS spotlight searches for github
I imagine the devs were wise enough to include "github" in the list of search keywords that you're allowed to attach to your App Store submission.
That will allow people to search there for github and see the app in the list of launchable items.

This has nothing to do with the appstore other than a way to get a keyword on the phone. The App KEYWORDS do not help the on Springboard Spotlight search.
