Unfortunately, there's a mismatch between the way GitHub packages a
".zip" and the way `raco pkg install` uses it. The GitHub-generated
".zip" file has an extra directory layer relative to the layout that
`raco pkg install` expects.

Specifically, "master.zip" has a "racket-bitsyntax-master" directory
that holds everything else, while you really wanted `raco pkg` to see
the "everything else". You can see the extra layer in the output from
`raco pkg`:
