Doesn't register correctly as macOS app

[noamzaks]

Hey, I don't know if this is part of homebrew-zathura or zathura itself, but it doesn't register properly as a macOS app.

Precisely, the following doesn't work: open test.pdf -a /opt/homebrew/bin/zathura

The application /opt/homebrew/bin/zathura cannot be opened for an unexpected reason, error=Error Domain=NSOSStatusErrorDomain Code=-10811 "kLSNotAnApplicationErr: Item needs to be an application, but is not" UserInfo={_LSLine=4129, _LSFunction=_LSOpenStuffCallLocal}

This may also help with #78.
