refactor def github_info in cmd/info because if statement is hard to read.

This doesn't make sense; if f.tap.nil? then f.tap&.remote is a pointless check because it'll always be nil too. I'd suggest keeping the ordering the same (rather than flipping the if/else) and, if better, use an early return.
