3 binaries after install instead of one

Hello,

I've noticed that after install I get 3 binaries

```
ls /Library/Frameworks/Python.framework/Versions/3.11/bin | grep bugwarrior

bugwarrior-pull
bugwarrior-uda
bugwarrior-vault
```

This seems to contradict the documentation, I tried installing from pip and from source just to see if there was something wrong with one of the installing methods.

Is this to be expected?

I'm on macOS.
